Update 井3636 2026-09-16.
Home
These are my homegrown tools.
A tool exists because I did not find its function builtin in Windows (at the time). Or because there was a specific use case, that was easier to solve like this. And auditing for malicious code is easier in a few lines of your own, than in something off the internet.
And writing code is more fun than reading documentation somebody else wrote. (Yes, I see the irony.) Or did not write.
And implementing your own bad version is good for learning 
. And 
What you want may well be in Windows:
Windows Commands 
,
or Sysinternals ,
or Powertoys .
Also search Qwant 
,
and check NirSoft 
.
Requires .NET, which should be part of a Windows installation. If not, get it from MS: .NET 4.8.1 
.
If you are on an old Windows version not supporting 4.8, options to try are .NET 4.0 (more likely to work, but out of support), or .NET 3.5 SP1 (still in support).
FileSorter, hTacho and PasteAnything also have an *35.exe build for .NET 3.5 in 35ers.zip, though some functionality will be missing by now.
Some .NET installation files (notably for Compact Framework) are kept here: NetFramework . Do read the ReadMe.txt .
Applications zipped: HenningsSoftware.zip .
This page and applications zipped selfextracting: EverythingForOfflineZip.exe .
Applications as separate files: Applications . Maybe use something like FromWebToHere.bat to keep up to date.
Extract the files you need to a local folder.
Ideally, the folder should be protected (meaning only admins can write) fex %ProgramFiles%\LazyCat\Tools .
You can use _ThisFolderInPath.bat to make access easier, especially if using command line tools.
GUI applications will create their own link in the Start Menu, similar to ClickOnce.
Some applications (hm, about 25%) use Windows Speech for notification, and all speak english. They preferably select a female english voice, and if one is not found it may sound less than ideal. (For comparison: hBeep, PowerMonitor and FixBluetoothAndSound use pre-recorded voice.) In Windows settings you can 'add speech voices' (I prefer 'English - Australia'). Adding voices will not impact other applications that use the Windows default. If speech still sounds wrong, see help and fix under Speak ; there should be at least one 'en-' listed available fex: 'Microsoft Catherine, en-AU'.
Delete the .exe from were you dropped it.
For GUI applications: Delete the .url from %APPDATA%\Microsoft\Windows\Start Menu\Programs\LazyCat .
For applications that autostart: Delete the .url from %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup .
For services: Look at the install script for "You could now exit this script and delete installation.".
Settings and internal data may be found in one of:
To open all existing run LCSettings.bat . Or copy path into RegEdit.exe or Start→Run.
Contact: lazycat@outlook.dk.
Where to find: hxo.dk. (Alternate murena.io.)
Things get added or modified when I need the functionality or get asked about it. There are many things in todo.txt. If you know me, and think there is something missing, I may have not come to it yet. Or it was started over with a new name. Or it was made on paid time, and has not (yet) been started over.
Origins of LazyCat are lost in the 1990ies, but have been used to distinguish personal 'code' from employer 'code' fex in the StartMenu, since I started.
And the hSomething naming? When I cannot come up with a better name (fex Search?), my first initial get added (hSearch), an idea taken from Amiga software, fex AREXX, AMosaic, ATerm ...
A few started on .NET1.1/VS2003, but 1.1 did not directly support serial ports, so .NET2.0/VS2005 was used very early after release.
No "AI" were used to write code or this page. I am much faster at catching my own errors, as opposed to first understanding and then catching errors someone or something else created.
The following descriptions and screenshots, are just to give an idea of each application, not full instructions. I do not update this page with every little change.
Go explore!
Last modified at top. Applications link to description on this page, other files open in the browser, so bat, reg and txt should be readable.
To get files see under Install .
Tip: Your cute browser may be hiding scrollbars ↓.
You should review, and in some cases edit, bat and reg files for your use. Some even have comments and links 😉.
Notice the titlebar? Simulate bold etc in places that do not support it like plain text files (Notepad.exe) or filenames or source code, fex:
Also see code points under ByteEdit
hCryptFiles. Henning Olsen. Release build: 2026-06-24T18:56:28Z
Encrypt and decrypt files from the commandline.
File:FileName More than one can be given.
Folder:FolderName
FilePattern:FileNameAndWildCard. Used with Folder. Default *.* .
SubFolders Include subfolders.
Watch:Seconds Watch Folder for changes, work after Seconds delay. Set delay for environment.
InPlace Replace source files. Use this OR OutFolder.
OutFolder:FolderName Copy To this folder.
OverWrite If existing Copy To file is different (unencrypted length+time) it is overwritten, else renamed *-hCF-DateTime.* .
NoLT Zero length and time written to header. This means encrypted and un-encrypted files when compared looks different.
Encrypt Encrypt.
Decrypt Decrypt.
Password:Password Careful: Commandline and bat files may use different codepages. Maybe use PasswordFile:
PasswordFile:Pathname Entire file (all lines, except BOM) read as UTF8 is used as PW.
PasswordDialog Ask for password in a dialogbox.
Salt:String Salt and Iterations are as important to remember as Password.
Iterations:Number Maybe leave at defaults.
ShowPassword To test PW encoding. Asks to show password in dialog box and copy to clip. Then just exits.
If password, crypt command, InPlace or OutFolder is missing, files are listed, not changed.
Encrypted files are prepended a magic UTF8 string for ID: hCryptFiles😸
Only files with the magic string are decrypted, and files with the magic string are not encrypted again InPlace.
To change encryption, first decrypt.
To remove extra files in destination use: RoboCopy.exe Source Destination /Purge /S /NoCopy
Stored unencrypted in header is unencrypted filelength and modified UTC time. See NoLT.
AES, IV in front, key from PW+salt via SHA512 in at least 1000 iterations.
Example for backup, see script under hWaitFor
Get any data anywhere you can get text: Paste in RDP or VNC, eMail, batch file...
To get PasteAnything.exe to the other end, use Bootstrap and follow the intructions.
Use selfextracting script to embed any file in fex a .bat file. Fex a help.html or an executable that is not expected on target machine.
Bootstrap and selfextracting script can seem CPU heavy, but that is because (some) AV software seem to scan the entire temp file for every line written. If the temp file, P!A, is excepted in AV, the unpacking is fast.
The break/unbreak functions are also used in fex hMail .
Little fun fact: Base64 strings get an extra newline every 50 lines, because the Lotus Notes mail system had/have a limit on paragraph length.
PasteAnything35.exe is build to .NET 3.5, and will work on XP/S2003.
Front for FFmpeg 
.
Example uses: Set two videos side by side, rotate, cut.
Very fast when only demux-mux is needed, such as with appending and cutting.
And faster for me to program the few things I needed, than learning to use
Kdenlive 
.
For some work HandBrake 
is a good option.
If output is .gif: Keep it smaller than 2GB.
hFFMPEG, Henning Olsen, Release build: 2026-04-02T09:57:55Z Commandline front for ffmpeg for scheduled conversion. InputFolder:FolderName SubFolders Include subfolders. InputFilter:String Fex *.wma . Default *.* . OutputFolder:FolderName Subfolders are created as in input. KeepTimestamps Use input files time on outputfile. OutputAudioRate:NumberUnit Fex 192k . OutputVideoRate:NumberUnit Fex: 2048k . VideoSize:WxH Default: Same as input. OutputType:String Fex mp3 . Note no leading dot. KeepOriginalExtension Fex when converting SWF to GIF in old website. LogFile:String Default log.log in current dir. RecodeExisting Default is to skip existing output files. Given this, files are overwritten. FFMPEGExe:String Pathname for ffmpeg.exe . Default is ffmpeg.exe, so have it in %path% or current dir. https://ffmpeg.org/ - Download the static build for Windows and unpack.
A front for FFMPEG as above.
I keep music in a lossless format on a home server, and run hFFMPEG from WatchFileEvents (or use SchTasks) to generate lossy WMA and MP3 for smaller devices.
Why use FFMPEG from the commandline and not as a library directly? My use of FFMPEG started with .bat files, so this was a natural continuation for these small tools. Also, using non-.NET code from .NET is plenty "fun" with something stable and well documented as WIN32. But something open source with Linux as the primary target?
Hangs around top of screen and shows hostname and username. Moves when mouse enters. Yellow when local, blue when remote.
Sets itself to autostart.
(Yes, I have the taskbar at the screen top, near were applications tabs also are. Makes for less mousing around.)
To uninstall an older version that was script installed for all users, run this script:
@echo Run as admin!
taskkill /im serverinfo.exe
hwaitfor.exe processstopped:serverinfo.exe
rd /s /q "%ProgramFiles%\Hennings\ServerInfo"
del "%ALLUSERSPROFILE%\Start Menu\Programs\Startup\serverinfo.lnk"
@pause
What it says. Always runs in the background.
Sources are folders where subfolders are seen as a unit. Fex Visual Studios projects folder or OpenSCAD drawings.
Destinations are folders where backups are kept zipped. See next image below.
Zips are kept in local buffer, until its destination is available. Each destination has its own cleanup rules. I keep a short backup on OneDrive and an unlimited on a home server.
Automatic diary. Runs in the background. Helpful for ideas for the timesheet.
Or when trying to remember where you got to in a video: In VLC 
Settings find "Change title according to current media" and set it to "$F $I $C $T". See VideoLAN Documentation .
SharedBatteryZip.exe or SharedBattery.zip
If you have a (small) UPS that supplies power to more than one PC, and it connects to one PC with USB (or possibly RS232) and presents itself as a battery to Windows, you can use this to distribute UPS/battery status to the other PCs.
Any number of UPS groups can be in a network if InstallIDs are unique.
There are two parts installed on each PC. A GUI for settings and quick status, and a service to read UPS and control shutdown etc. Service also logs status.
Install with .bat and set (inbound) firewall rules.
In my network an always on low power matchbox server (Atom 1,6GHz 1GB 
) is the Dictator. If there is no Dictator broadcasting, Followers take no actions, but there will be a warning in log and GUI.
Mail will have the following headers (View Source) for easy filtering in your mail system:
PathManage - Henning Olsen - Release build: 2026-04-02T09:58:54Z Used to manage the %path% variable from the commandline. Any number of the switches can be used: Prepend:Path Add new Path to front of %path%. Append:Path Add new Path to back of %path%. Delete:Path Delete Path from %path%. Case insensitive. Trailing \ is ignored. Clean Remove duplicates. Target:User or Machine Default:User. Only one target at a time. Duplicate entries are removed. Current paths: C:\Program Files\LazyCat\Tools C:\Users\henning\OneDrive\SW\ffmpeg\bin\
Typical use is in installation scripts.
Process scanned books. From one or more files like:
To:
Also creates html files for viewing and printing (HTML files have pagefeeds when printing (Tested with Firefox Save to PDF, and Firefox + Microsoft Print To PDF).)
Embedded image HTML is portable as single file. This fex makes it viewable with mobile browsers, that restrict filesystem access. More info under: HTMLEmbed .
(2024-09: Just noticed the browser on a test i-🍏 fails on largish files. But Firefox 
on /e/OS 
and Edge on a WP10 Lumia 650 
are OK.)
Example outputs:
ReplaceText - Henning Olsen - Release build: 2026-04-09T11:34:36Z Switches: HexEncoded, *after* this switch, content of ReplaceX and WithX is read PE fex *0D*0A for newline. ReplaceX:String, string to replace. X can be any string linking a Replace and With pair. WithX:String, with this string. Replacing is done in order of Replace. RFileX:FileName, filecontent to replace. WFileX:FileName, with this file. Replacing is done in order of Replace. InsertBR, replace CRLF with <br> . Must be followed by ReplaceHTML. ReplaceHTML, replace < > " & ' with < > " & ' . Done last. IgnoreCase, default is case sensitive. FileIn:Pathname FileOut:Pathname FileOut and FileIn can be the same. Thankyou for that MS!: If a double quotation mark follows two or an even number of backslashes, each proceeding backslash pair is replaced with one backslash and the double quotation mark is removed. If a double quotation mark follows an odd number of backslashes, including just one, each preceding pair is replaced with one backslash and the remaining backslash is removed; however, in this case the double quotation mark is not removed. So if fex you want replaceA:G:\Data\ you must write replaceA:G:\Data\\
Example use is the script building this page: Modified time and filelist are inserted with RT.
Another has been modifiyng autogenerated GB sized SQLCMD scripts during migration.

Used when managing printers; batch update; setup Zebras; fault finding: What was sent to a printer, where in the chain did the job get damaged.
Converts any image to a format that Zebra printers can understand. Images can then be used in own label designs. Known to work on printers (would depend on firmware) from ~2000 to 2023.
I have used it for my own label applications, including the conversion code to dynamically create label images. And it was used for label content to be printed from a wellknown ERP system. Hence the rotation options.
(I think this is the only application I ever made, where a '2' replaces 'To' in the name. Have annoyed me for a long time.)
As per image. Can save and load/merge results for later comparison. Merge can be done with OpenWith→ChooseAnotherApplication.
Also works from the commandline:
Hash - Henning Olsen - Release build: 2026-06-09T12:26:12Z
Single argument opens GUI with argument loaded as file.
File:PathName Add file to list.
SubFolders Must come before Folder:.
Folder:PathName Add files in folder to list.
OutFileXML:PathName Internal .hashlist format.
OutFileTSV:PathName
MD5
SHA1
SHA256
SHA512
Calculate time, use as kitchen timer, any instance Saved will autostart at next login.
Nothing special, except maybe the randomizing of targets.
Did the FW team do what they said? Use this to see if TCP or UDP gets through, possibly before the HPCs get to install their applications.
Lost a device due to misconfigured IP? Setup in the same network or better direct connection, and listen for noise from the device and note its IP.
Blinks NICs off and on, so its patch is easy to find at the switch. Or use 'One time.' to 'restart' NICs.
But I have this network tool with ID plugs!
And you always lug that around? Or have never dealt with a server with multiple NICs (numbering is always different between HW and OS)?
Power - Control machine and monitor power - Henning Olsen - Release build: 2026-04-02T09:58:57Z Lock LogOff Disconnect Shutdown Restart Hibernate Sleep DisableWakeEvents - Used with Hibernate and Sleep MonitorOff MonitorOn Delay:Seconds or Delay:mm:ss or Delay:hh:mm:ss . More than one command are done in order.
Control machine- and monitor-power from scripts.
If fex an installation needs a restart to finish but you want to leave the machine off or in sleep use: RestartAndSleep.bat.
Password generator. Loved by web devs that think they handle unicode. And users. Users love it.
FolderCompare - Henning Olsen - Release build: 2026-04-02T22:05:56Z
Compare files in a number of folders.
Folder:Name Multiple folders can be given.
FilePattern:*.* Default *.* .
ExcludeFile:Name Exclude files with this exact name. Fex desktop.ini and thumbs.db .
ExcludePartFile:Name Exclude files with this in the name. No wildcards
ExcludeSmallFiles:bytes Exclude files smaller than bytes.
SubFolders Include subfolders.
File:Name Specific files to compare.
CName Compare file name.
CPathName Compare file relative pathname from root folder. Use with multiple folders.
CModified Compare file modified timestamp.
CModifiedRelaxed Compare file modified timestamp relaxed, +/- 5 seconds.
CSize Compare file size.
CHash Compare file hash. Default SHA512.
SHA1 Use SHA1 hash. Might be faster on older CPUs.
ResultFile:Name Output result to Name-diff.TSV and Name-equal.TSV and Name-errors.TSV .
ListOnlyDiff Only list differences.
ListOnlyEqual Only list equals.
If result is too much to show on console and no ResultFile is specified, ResultFile(s) will be saved in %Temp% .
If runtime is longer than 20s, beep when finished.
Compare files in a number of folders, by a number of properties.
Antivirus SW can drastically slow down hashing, as it scans files being read.
Comparing a list of n files takes n * (n - 1) / 2 comparisons. 100 files is 4.950, 1.000 files is 499.500. 10.000 files is 49.995.000.
ReadFiles. 2022 Henning Olsen. Release build: 2026-04-02T09:59:20Z Does nothing but read files. Before reading, the found files are sorted in the current language by pathname. Folder:Name....One or more rootfolders. File:Name......One or more files. Subfolders.....Include sub folders. LowMem.........Use smaller read buffer. Slow...........Insert pause between buffers. Includes LowMem. OpenOnly.......Only open files, do not read data. Can be used with OpenWrite. OpenWrite......Open file with write access. Used for access test, no write is done. Log:PathName...Appends to existing.
May seem silly. Example uses: Read all files on storage disk to trigger errors to SMART or check access errors.
SpotDynDNS - Henning Olsen - Release build: 2026-04-02T09:59:50Z Domain:DomainName The domain to test. Port:Number TCP Port to test. (This port may need NAT forwarding in router to this host.) Timeouts:ms Timeouts for connections, default 4000. CommandProcess:String Command to run at start and when connection fails. CommandHTTP:String HTTP URL to call at start and when connection fails. CommandHTTPTimeout:s Timeout for HTTP command. IgnoreCertErrors To force IPv4 or 6, URL is reformatted with IP, which means HTTPS usually fails. IPVersion:Verson Both, V4 or V6. Default Both. CheckInterval:Seconds Time between connection test. Minimum 10, default 60 UpdateInterval:Seconds Minimum time between running commands. Minimum 60, default 900. UpdateAnyway:Hours Update regardles of succesful connection to keep account active. Default 240. LogFile:PathName Default no logging. Remember "" around switches, CMD splits on &. With dynamic IPv6 you should set: netsh interface ipv6 set privacy state=disabled to disable temporary addresses.
Updates DynDNS service when [router outside] IP changes. Should be run in SchTasks with a minimal user.
At every CheckInterval a TCP connection is tried to DomainName:Port. SpotDynDNS listens on the port with a handshake. If connection fails, it is assumed IP has changed, and one or more Commands are executed to update DynDNS.
(I have used dyndns.dk 
since about 2000.)
Copy, filter, edit and merge contact lists. Convert between formats, CSV (Outlook), Nokia and VCF/vCard (Android/Thunderbird/etc).
CSV could work for other applications as well.
(I think desktop Outlook fell over when importing non-ASCII, but that could have been the en-US deployment, and I cannot check now, nor do I really care. OWA was and is fine.)
When started it will hang around in the Systemtray.
Clicked it will take the content of the Clipboard and:
Text will be returned the the Clipboard with formatting removed.
List of files (marked for copy in Explorer) are returned as text list, fex:
L:\TXT\TXT\bin\Release\TXT.exe
L:\TXT\TXT\bin\Release\TXT.exe.config
L:\TXT\TXT\bin\Release\TXT.xml
If the Clipboard contains an image, you will be asked for a file name to save it.
If right-clicked the result will also be shown (image is not saved).
If middle-clicked text is made into VB comment.
HotKeys: CTRL + ALT + T = LeftClick, Shift + ALT + T = RightClick, CTRL + ALT + C = MiddleClick.
SetBasePriority. (c) Henning Olsen 2014. Release build: 2026-04-02T09:59:35Z
Arguments:
"Interval:Seconds" Default 60.
If a process cannot be accessed, its ID is ignored for 10 intervals, error message is written to console.
"ProcessName:Priority"
Processname is not case sensitive.
Do not include .exe in processname.
If ProcessName starts with * it is considered partial.
More than one processname can be given.
OneRun Exit after first round, do not keep running.
Don't forget to enclose arguments in "" if they contain spaces.
Run as admin to touch other sessions.
Examples:
SetBasePriority.exe *ServiceHub.:BelowNormal interval:10
SetBasePriority.exe noTepAd.exe:idLe
Priorities:
Normal
Idle
High
BelowNormal
AboveNormal
https://learn.microsoft.com/en-us/dotnet/api/system.diagnostics.processpriorityclass
Possible exitcodes:
Defaults to hang around and sets priority for given processes.
Run from SchTask with elevated account as needed.
Example uses have been non-cooperating server applications with equally non-cooperating vendors.
Or the work PC where AV scans would make the MP stutter the music: Increase priority for MP.
And I use SetBasePriority.exe *ServiceHub.:BelowNormal interval:10 , to speed up the rest of VisualStudio... 🤷
Another VS speed up is, after updates, to run C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ngen.exe executeQueuedItems . See comments in NGenLazyCatExes.bat.
Use when trying to understand some applications undocumented DB. Start with a bit of data you know is there and related to what you want, and follow the relations.
Why not use a mapping tool? Sometimes that is too much or not available. Or you get a DB with 450 tables and no foreign keys.
Search. Search and Replace. Encoding aware. Convert between encodings. Find big folders.
Open Search can be done with OpenWith→ChooseAnotherApplication. If doing this, a new search can be started from the Start Menu: Click Clear, setup search, Save search and open the file once from Windows. Or just use History.
Irritates me less than Windows search. Since XP...
Blocks specified processes or windows.
As stupid as it reads; one important use was blocking users from shutting down terminal servers. Users that were admins because the server owner did not want to deal with the applications vendor, so it could work with limited accounts.
Or fex keep intrusive things down: blockwindow.exe processname:RUXIMIH processname:OfficeClickToRun processname:msedge partialprocessname:oobe killprocess period:0
Example use is when working with Remote Desktop in full screen. Keeps "Corners", the little squares
Client→
Client view of server→
Server→
always visible, that when clicked brings up
that let you chose another application on client or server.
Run As Admin if you want to see what fex installers or Windows are up to.
I also use it to trigger actions, fex to run hFFMPEG when the sources changes.

ExitCode is 0 when no errors are logged.
Copies file or folder from http, UNC or local.
RenameOldFile is useful when the file is locked/InUse or in a backup script where old versions in backup should be kept. This function, I believe, is missing from RoboCopy.exe?
Example twoway sync:
START GetWebFile.exe "GetFolder:\\Server\Share" "SaveFolder:T:\Sync" SubFolders SkipSame SkipNewer RenameOldFile SkipGWFFiles Watch WatchAge:20 WatchRestart:1440 START GetWebFile.exe "GetFolder:T:\Sync" "SaveFolder:\\Server\Share" SubFolders SkipSame SkipNewer RenameOldFile SkipGWFFiles Watch WatchAge:20

SetAutoRun 2010 Henning Olsen Release build: 2026-04-02T09:59:34Z Adds "File:Name|Switches" to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run or HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce or HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run or HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce with switch "Machine" or "User" and optionally "Once" . More than one file can be given. "MachineDelete" or "UserDelete" will delete entries from either hive. Machine* requeres admin rights. Exitcode is 0 on success.
Use in setup scripts.
DateTimeCMD - Henning Olsen - Release build: 2026-04-02T09:57:11Z Sets variables in Process and User: hDate, hSecond, hMinute, hHour, hDayOfWeek, hDayOfMonth, hDayYear, hMonth, hYear, hGUID hDateUTC, hSecondUTC, hMinuteUTC, hHourUTC, hDayOfWeekUTC, hDayOfMonthUTC, hDayYearUTC, hMonthUTC, hYearUTC Date format: yyyyMMdd_HHmmss.ffff - 20260403_163129.1218
Set environment variables with date and time information. And a GUID.
Yes it works, but as with most things with environment variables, it does not work as you expect.
SetVar 2016-07-08 Henning Olsen How the hell is this not a builtin function? https://devblogs.microsoft.com/oldnewthing/20120731-00/?p=7003/ First argument is the variable name Value:String. Optional. If not given, value is read from stdin (pipe |). Target:Machine/User/Process. Optional. If not given Process is assumed. List:. If this is the only argument, all variables are listed.
Sets environment variable from output (piped) of another process.
As above: Yes it works, but as with most things with environment variables, it does not work as you expect.
SetErrorlevel 2016-07-08 Henning Olsen If one argument is given, it will be parsed to a number and used as exitcode. If no argument is given, stdin (| pipe) will be read, and it will be parsed to a number and used as exitcode. If the value cannot be parsed, exitcode will be -1 ERRORLEVEL is not %ERRORLEVEL%, see https://devblogs.microsoft.com/oldnewthing/20080926-00/?p=20743/
Use in scripts.
Saved me many OS restarts when using Teams. Teams seemed very happy to change audio patching in Windows, and then complain "Your mic is not working.". I came to prefer using the Teams web application in Firefox...
Use Sound Check Sync, to see if AV is out of sync in the source or Windows/Audio/Bluetooth. The latter can be fixed. (I have a no-wires-at-all 
headset, that seem more prone to this.)
Use Sound Check Tone to know if any sound is working. The lower and higher frequencies may not be heard with all hardware or ears.
Use Sound Check Channels to know if sound is going to the correct side, or if the two sides are different.

Masks first 4 bytes of file and prepends 'HO%00'. Use if stupid mail admin blocks zip on signature. UnbreakZip:File name, reverse BreakZip. RetrySeconds:Seconds, time between retrying sending, minimum 30s default 300s. RetryLimit:Times to retry, default 0. When more than one is allowed use the form: file:file1 file:file2 Don't forget to enclose arguments with spaces in "" Outlook.com server: "Server:smtp-mail.outlook.com" "ServerPort:587" "SSL"
Send mail from the commandline.
Files can also be unbroken with PasteAnything .
Started as a tool to lock session and turn off monitor, ignoring if fex a media player requested presentation.
Since early 2023 Windows 10 no longer starts screen savers, so screen savers was added. Option to use any executable as "screen saver".
(Group Policy settings passes to ControlPanel, but have no effect. PowerCfg.exe does not list any blocking requests, and monitors power off as expected. Several PCs (Win7/8 upgrades and fresh installs) with different GFX vendors...)
All controls have a tool tip on hover.
Sets itself to autostart, and then "hides". To change settings click link in StartMenu.
To push machine wide settings copy the settings file from %APPDATA%\LazyCat\hLock to %WinDir% . Maybe use AD and GP for this.
Screen saver. Shows images, sound and video files in selected folder.
Install by copying content of hAVscr.zip to %SystemRoot%\System32 .
Set settings in Windows Screen Saver Settings, or use hLock.
All files that Windows Media Player can show should work.
Install by copying KatScr.scr to %SystemRoot%\System32 .
Set settings in Windows Screen Saver Settings, or use hLock.
Another screen saver.
Install by copying hSCR4.scr to %SystemRoot%\System32 .
Set settings in Windows Screen Saver Settings, or use hLock.
.mp4
Another screen saver. I thought this already existed, but no. This have the same visual effect as hSave2, slowly cycling all colors. On average it takes about 11 minutes and 11k color changes, before a color is repeated.
Install by copying hSCR1.scr to %SystemRoot%\System32 .
Set settings in Windows Screen Saver Settings, or use hLock.
Primary example use was 'a wall' of computer screens on the office wall for monitoring and status.
But people would forget to turn them off at night, leading to tired pixels 
. Or worse; forget to turn them on in the morning, so there were 'nothing to see'. (Yeah, I know.) So this was made. See tooltips and the help page for how it works, it is really simple.
This one I know is from 2006-01 or earlier, so .NET1.1, and now took a bit of work to get to 4.8.1, with updates and modernisation.
What is it with the pink copyright infringement?
Someone did not like the original icon, because it "... is too angry... ". I forget the details. But I changed to this icon, the least angry I could think of, and as it was all on my own time, the complaints stopped.
Runs an alternating black and white line down the screen every minute or blink B/W dots at random locations. Dots are less noticeable, but maybe less efficient.
Did seem to reduce burn-in on plasma and CRT screens with static image parts. And possibly fixed "lazy pixels" on early LCDs. Still in 2023 I just use it on anything that shows static images.
Elevate - Henning Olsen - Release build: 2026-04-02T09:57:16Z First argument must be Wait or NoWait or Begin (or End). With Wait or NoWait the following arguments are run as if from an elevated CMD. Exitcode is 0 on success. Examples: Elevate.exe NoWait Notepad.exe "%SystemRoot%\System32\drivers\etc\hosts" Elevate.exe Wait Install.bat /AllUsers With Begin the next argument is a batfile, in which is found the first line beginning with 'Elevate*.* Begin/End'. From the rest of the batfile parts between lines 'Elevate.exe Begin' and 'Elevate.exe End' are copied to %temp% and run elevated. Other parts are run un-elevated. Wait is implied. To point to the current batfile use '%0 & exit', example.bat: Elevate.exe Begin %0 & exit NetStat -a -b -o >"%temp%\ns.txt" Elevate.exe End Notepad.exe "%temp%\ns.txt"
Use in scripts. Runs an .exe or .bat or parts of a .bat as Administrator, opening the UAC prompt as needed.
The Flash in the name is from flash drives (USB or cards) that are used where encryption is not possible. FW is not 🧙 faster than the drive.
Another use is testing if a dodgy drive is really of the sold size. Or stress- and speed-testing.
FlashWipe works by filling empty space on the selected drive with data.
If the drive is in use by other applications, a part of the drive may not be filled. Also, a drive may have copied data off a bad area, from which it could potentially be read when deleted from the new location.
How good is the wipe?
Good enough. And works without admin rights. Also see:
Toms Hardware, Securely Erase an SSD or HDD 
.
When possible, always use drive encryption, such as BitLocker. Do not expect to be able to (fully) wipe a drive (before you lose it or send it back under warranty).
Do not transmit or store unencrypted data: Use encryption!
DeleteOldFiles, Henning Olsen 2021 Release build: 2026-04-02T09:57:12Z Folder: Where to start. FilePattern: Default *.* . Subfolders Include subfolders. MatchFolder: Only delete file if foldername contains this. No wildcards. DateTime: Cutoff. Must be in format: 2026-04-03T16:14:02.7470627+02:00 Minutes: Cutoff. Hours: Cutoff. Days: Cutoff. If more than one cutoff is given, the last on the line is used. ShowOnly Only list files that would be deleted. Exitcodes: 0 - OK, 1 - Argument error(s), 2 - Run error(s).
A GUI for HTMLEmbed .
HTMLEmbed - 2023 - Henning Olsen - Release build: 2026-04-02T09:58:16Z HTMLEmbed takes a HTML with its images etc locally saved, and embeds images etc in the output HTML for easy portability. Save a web page from a browser, or save a document from fex MS-Word or LibreOffice Writer. In both cases do 'Save as Web page complete', which typically gives a HTML file and a subfolder with images etc. (HTMLEmbed can try to fetch files via http, but your browser is *much* better at assembling the page.) Some "complex" pages render wrong after being saved (and embedded). I have good experience with first changing to Reader View ([F9] in Firefox) and then saving. If output has unexpected characters, input could be in something else than UTF8. Look in the source for 'charset=ABC'. For HTMLEmbed then specify "Encoding:ABC", likely Encoding:Windows-1252. Outfile can be up to 2GB. Each embedded file can be close to 1GB. Browsers have their own limits. "InFile:PathName" "OutFile:PathName" "FixOutName" RemoveSpaces. "SkipEmbed" Must have used it somewhere. "SkipVideo" Do not embed video. "SkipAudio" Do not embed audio. "StripScript" Remove script tags. "StripComment" Remove comment tags. Fex if source is Word, some data is doubled in conditional comments. "LineBreaks" Insert line breaks in embedded files. Files in <style> never get linebreaks. "HTTP" Also fetch files by HTTP. Is always on if InFile is by HTTP. "Timeout:ms" HTTP timeout, default 500ms" "Encoding:EncodingName" If no EncodingName is given, possible encodings are listed. "LeaveTemp" Downloaded files are left for other uses. See foldername when finished. "NoNote" Do not place note at start of output. Maybe use if target browser is older. "DebugInfo" More detailed error messages.
This page as an example:
158.405 input bytes.
158.310 input chars.
346 IMG tags in InFile, 345 replaced.
1 VIDEO tags in InFile, 1 replaced.
0 AUDIO tags in InFile, 0 replaced.
1 REL tags in InFile, 1 replaced.
2 url('') tags in <style> in InFile, 2 replaced.
16.758.152 base64 chars total.
16.910.664 output chars total.
16.910.882 output bytes.
Errors:
FileSrcToBase64Src, no file? XXX.png
This (and TrimMultipageScans ) uses data URI , an alternative to MHTML files, which have very little support nowadays.
Makes portable HTML with images etc embedded. This fex makes it viewable with mobile browsers, that restrict filesystem access.
hWoL - Wake On Lan - (c) 2008 Henning Olsen - Release build: 2026-04-09T11:33:36Z mac:MAC-address in hex. macfile:text file with a single MAC per line. MAC-addresses can be given with any delimiter. bca:IP-addr/hostname The broadcast address to use. bcafile:text file with a single IP-addr/hostname per line. If no BCA is given 255.255.255.255 is used. repeat:count, default is 0. port:UDP-port number, default is 9.
Wake on Lan. Works in VLANs and through NAT if configured in the network equipment.
Settings to enable WOL can be found in BIOS/UEFI setup and Network/Device settings. Each PC/OS/Driver is different, here is a typical Windows example, BIOS/UEFI on this PC has nothing related:

Example uses is with resource constrained PCs or if recipient cannot use something like 7zip or cannot recieve self extracting archives.
FileSorter35.exe is build to .NET 3.5, and will work on XP/S2003.
As FileSorter will run on most Windows versions, here is how it looks on XP (Duplo), XP (Adult), 7, (sorry no current 8), 10, S2019, 11 and S2025:
I find XP & 7 easier to "read", as the different control states have, well, more difference.
Each application can chose to use the older style, but it will then look out of place. To see it, play with Style in WhatHaveIDone
Run As Admin if looking at "live" log files.
Doing reverse DNS on client IPs can be very slow at first, but IISlogView caches results over restarts.
Also reads Apache logs, if they follow
Apache doc 
default Common Log Format + Combined Log Format. HostnameLookups is allowed.
Example entry: 20.80.98.152 - - [11/Sep/2026:01:08:55 +0000] "GET / HTTP/1.1" 200 5362 "-" "Mozilla/5.0 zgrab/0.x"
That is an annoying format; space separated values, datetime with space, but in brackets and not quotes. And datetime in that format. Oh, and quotes are not escaped...
Keeps a clear transparent window on top of everything on all monitors. Can be unlocked with Windows password. Shown above is the unlock screen over the desktop.
Hides mouse. Does a variant of BlackBar. Click anywhere to get to the above screen.
Example use is for a PC to stay unlocked showing some application like a spreadsheet that does not have a "kiosk mode", but there is a need to keep people out.
Not super safe.
Keeps a transparent window on top of everything on all monitors.
Can be unlocked with Windows password or password local to GlassDoor. PW could be a simple PIN.
Sets up autostart. Option to keep Windows session from locking when GlassDoor is locked.
Example use is a PC that must be locked, but where onscreen information must be viewable.
FileToVBArray - Henning Olsen - Release build: 2026-04-02T09:57:22Z Encodes one or more files as a class.vb file with the files content as arrays. Example use is alternate way of embedding data. Maybe call as pre-build event. InFile:PathName, more than one can be given. Filename with . removed is used as arrayname. OutFile:PathName, filename without extension is used as class name. Password:Password, optional. If given data is embedded encrypted. Salt:Salt, optional. Iterations:Number, optional. Default 1000
Encrypted (optional):
Clear:
Encodes one or more files as a class.vb file with the files content as arrays.
Example use is alternate way of embedding data. If called as a pre-build event, add the class file as linked.
Note that the resulting class file is a few times larger than the input or compiled files: If the file is big, do not try to view it.
The compiled content is the same size as the input. (For small files as in the above examples, the overhead of initialization vector (16B) and padding (0-16B) can be large.)
This functionality started in another application when:
Corp AV Scan Jockey: Your application X contains a string that looks like a web address.
Me: And that is a problem?
CASJ: It can be used to download malware.
Me: It is for an internal webserver.
CASJ: [Silence]
Me: [Makes and uses HideData.] Fine, here is a version of X "without" a web address string.
A few days later the new version is allowed to run.
WebPing (c) 2018 Henning Olsen. Release build: 2026-04-02T10:00:09Z Use:Run at server or workstation, access application from webbrowser fex on phone. If public facing, use the BlockIP options to hide local net. Arguments: PortNumber:Integer - Listenport. BlockIP:String - If a host has *any* IP, that starts with String, the result is as if the host does not exist. Any number of BlockIP can be given. Possible exitcodes: 0 - OK 1 - ErrorUnhandledException 2 - ErrorUnknowArgument 3 - ErrorLoadingSettings

OnNetworkChange 2022 Henning Olsen. Release build: 2026-04-02T09:58:51Z Logs and runs commands on changes (10s) to NICs. Arguments, both optional; "File:LogFilePathName" ; "Command:Something.bat". Started. Waiting for change..............
Fex use this and hMail to notify on IP change.
An early version of HN was in a group of HelloSomething applications made for end users, to quickly check the background status of "their" "system". This version only shares the name and basic idea: A simple network monitor.
When Autorun is enabled, the main window minimises to the Systemtray 
, and HN has become a start menu for my network with Wake, RDP, Shares...
Can be started at boot from SchTasks with NoGUI, for just logging and sending mail/SMS.
Mail will have the following headers (View Source) for easy filtering in your mail system:
This one is old (2005?), and at the time there was no quick way of following disk load when working. It is also lighter on CPU than modern TaskManager when only a simple view is needed.
(The PC that build all this is a 1,1GHz 4 Core Celeron 
, and TM will easily take 10-20% of that depending on view.)
And I have other ideas that will use Performance Counters, so this was also a revisit for that:
If started with a commandline argument, all Performance Counters are listed in a file with that name. Names follow en-US format (WTH are they localized?), as that is what I have to use when requesting the same counter on machines with different language settings.
Some counters are only listed when Run As Admin, although they may be available when queried directly.
hTacho35.exe is build to .NET 3.5, and will work on XP/S2003.
Crash - Henning Olsen. Crash is all. Unhandled Exception: System.ArgumentException: BOOM! at Crash.Module1.Main() in l:\Crash\Module1.vb:line 7
Example use is to validate settings from UserModeCrashDump.reg or Crashed_SchTsk.xml works as expected.
Measure time and screen elements. Also seems to work correctly with Windows Magnifier.
Maybe for error and status codes? 10400940?
Get content of all WinEvtLogs for the selected period in a TSV file.
Events are default sorted by timestamp.
The idea is to help if you do not know where to look, but know the time of an incident. And see timing of events between logs.
Inside the application, events that are or could be related to power transitions are filtered and shown with descriptions.
Maybe need to Run As Admin or at least be in the "Event Log Readers" group.
Windows has 1000+ EvtLogs, many of which are not active by default:
This never became a good byte editor, but changed direction (with no name change) and became useful for playing with ASCII and UniCode. And printers. Lots of Zebras and labels 😑.
Supports OpenWith→ChooseAnotherApplication. Or use Applications/ByteEdit.reg, which like Applications/Notepad.reg adds an entry to Explorers context menu:
Installs as service:
Unpack zip and run .bat.
Copy SettingsExample.xml or rename (a new example is always created at startup) to Settings.xml, edit Settings.xml and restart service.
Setup OS firewall to limit scope of remote addresses, fex to Local Subnet. Communication is not encrypted!
Gives options for Remote Control for controlled Restart, ShutDown, Sleep, Hibernate and Process and Session info even if OS resources are exhausted.
There are also options for a rudimentary telnet server: CMD and CMDSys differs in that CMD runs with a requested user account, and CMDSys runs in hRCs service account (default LocalService).
An option is only enabled, when a password is configured for it: That means nothing is enabled by default. See SettingsExample.xml below. A blank PW means no PW.
Connections (max 5 pending) and login attempts (1 pr s) are ratelimited.
Why? - If there are no out of band access like a virtual hosts console or physical remote access controller, fex because of home-grade servers or "slow" (any meaning you can think of) corporate jockeys.
Is this a bad idea? - Yes, in most cases. Move on and buy a RAC.

Enables or disables QuickEdit in this console session, fex to avoid accidentally "hanging" a script (showing Select in title).
(2024-11-11: Just noticed: Still works on W7, but not fully on W10; QE is correctly disabled when using internal commands like DIR, but flags get reset before external commands like PING.EXE.)
Add as Pre Build Event to the project. Adjust pathnames.
All projects, if they are not build at the same time, can share the same files; exe and vb.
When executed, it creates, in its own folder, BuildTimeStampModule.vb, as seen above.
On error, it retries a few times, and possibly exits with exitcode 1.
In the project, Add Existing Item, select BuildTimeStampModule.vb and Add As Link.

Speak from the commandline. I thought this was build in, but that may have been Amigas narrator.
(This page takes 60+ minutes to read!?)
Maybe create your own Windows sounds, so you do not need to discern 70 dings, but can understand directly what happened.
Or make VisualStudio speak with MakeVisualStudioSounds.bat:
I especially like the BreakPointHit and BuildFailed, as I like to get up and do other things when waiting.
Or make Windows yell, when the PC needs a charger with MakeWindowsSounds.bat.

Options to change recipients; fex many small devices, and changing crew, address change can be done in one place.
Example use have been when main mail server have been far away on the other side of a lumpy network, or to share a single FW rule with many 'unsafe' devices.
When a server has a folder defined, mail gets copied to folder as .EML files, and not sent with SMTP.
Weird, is one mouse button broken in just one application, or is it starting to break, only showing there due to timing?
Now also checks keyboard presses, so another application I should rename.
This does not listen for WindowsMessages, it just uses Forms events.
MakeIndexFiles - Henning Olsen - Release build: 1.0.0.350 - 2026-04-02T09:58:39Z
Makes index.html pages for webservers. But with options *I* like. Can also create pages with images.

Do read up on the settings and make sure they are right for your setup.
Makes 'index.html' pages for webservers. But with options I like. Can also create pages with audio, video and images.
Can hang around and watch for changes.
Examples:
Creates links that highlight specified text on linked page.
Example from screenshot above.
MPFiles - 2026 - Henning Olsen - Release build: 2026-09-02
Multi Process Files. Similar functionality to builtin ForFiles, but will split work up in parallel.
Folder:FolderName - More than one allowed.
SubFolders
FilePattern:*.*
FileNewer:Seconds - Or mm:ss or hh:mm:ss or dd:hh:mm:ss.
FileOlder:Seconds - Or mm:ss or hh:mm:ss or dd:hh:mm:ss.
FileNewerDate:2026-09-02T11:51:25.2705778+02:00 - Or partial fex 13:13 or 2020-01-01. Partial time is today.
FileOlderDate:2026-09-02T11:51:25.2705778+02:00 - Or partial fex 13:13 or 2020-01-01. Partial time is today.
Time is LastWrite and exclusive.
File:FileName - More than one allowed.
ListOnly - Only list selected files.
Command:Name - Exe, Bat, etc. If no Command is given, each file is run on its own with switches.
CommandSwitches:Text - Get filename with ** . Use double " if " is needed for command switches. Fex:
MPFiles.exe Folder:C:\Temp "FilePattern:*space test.mp4" "Command:C:\Program Files\VideoLAN\VLC\vlc.exe" "CommandSwitches:""**"""
Priority:Normal Idle High BelowNormal AboveNormal
https://learn.microsoft.com/en-us/dotnet/api/system.diagnostics.processpriorityclass
Minimize - Minimize window running Command.
Parallel:Number - Default is the number of logical CPUs. This machine: 4.
If negative, the value is subtracted from CPU count. Parallel will always be at least 1.
Randomize - Randomize filelist to potentionally spread load on different resources fex disks.
Exitcode is the negative sum of absolute exit codes from started processes. Positive code is from MPFiles.
Process files in parallel.
TCPToFile - (c) 2017 Henning Olsen - Release build: 2026-04-02T09:59:55Z InputPort:Number. TCPTimeOut:Number. Default 2000ms SaveFolder:Text. SaveFile:Text. If not specified, a random name is used. PrependFileNumber. Tries next higher number until the name is not found. Command:Text. CommandSwitches:Text. Get filename with ** CommandTimeout:Number. Seconds before killing that proces. Default 30s. DeleteFile. Delete file after command. Don't forget to enclose arguments with spaces in " Very simple example: InputPort:9100 "SaveFolder:C:\Temp" SaveFile:tcptofilefile PrependFileNumber "Command:notepad.exe" "CommandSwitches:**" Possible exitcodes: 0 OK 1 NoArguments 2 ErrorArgumentUnknown 3 ErrorInputPort 4 ErrorTCPTimeOut 5 ErrorCommandTimeOut
Run from SchTasks.
I think TCPToFile came to be, when either MS or BigCorp blocked printer port monitors from saving to file, though I have used something like TTF years before. And this has more functionality, fex using the Command option to send the 'printed' file with hMail .
Not only for picking up printjobs, but that has been a frequent use, fex dumping an extra copy of a print on a file server, or sending the same print to more than one printer, or buffer and only print during office hours with SchTasks.
Example printer port setup, start in PrintManagement.msc:
Wait for events in users session state, and execute commands.
Use when doing screen shots/capture (like with images on this page). Or when presenting, to show/hide parts of shared screen.
↓ ↓ ↓ ↓ ↓ ↓
Or just to show a clock. Any size, even fill all screens. I need a clock I can see from a distance, I will just put it in BackGround. That got a little out of hand.
hWrite - Henning Olsen - Release build: 2026-04-26T09:03:12Z
Writes text to file or console.
"Text:Text" - " in text must be doubled, see ""en"" in example.
"LineBreak:Text" - Default !! .
"Enc:Encoding" - Default UTF8. See next:
ListEnc - List available encodings.
Console - Write to console.
"File:PathName" - Write to this file.
"Timestamp:Format" - Append timestamp to filename, default format is _yyyyMMdd_HHmmss.ff
Prepend - Prepend, otherwise overwrite.
Append - Append, otherwise overwrite.
Example (note the double " around en in the Text argument to get single " in output):
hWrite.exe "File:%temp%\Output.html" "Text:<!DOCTYPE html> <html lang=""en""> <head> <title>List of C drive.</title> </head> <pre>No sub dirs.!!!!" LineBreak:!!
DIR C:\ /B >>"%temp%\Output.html"
hWrite.exe "File:%temp%\Output.html" Append "Text:</pre> </html>"
(I had to rename from Write to hWrite, because there are Write.exe stubs, for starting Wordpad.exe, in three super protected Windows folders, which meant sensible Path variables did not work, and scripts just started Wordpad.)
Originally a WinCE application (that will be published later when I need it), so some things can look strange.
All combinations of speeds, databits, stopbits and handshakes can be tested in one go.
HandShake is rarely needed, but the RTS or DTR line is sometimes (surprisingly) expected to be set by (older) devices, so I default them on in applications.
CS2 works on any port that is presented to Windows as a COM port. This includes RS232, RS422 and RS485, the latter used with fex MODBUS and PROFIBUS.
With two ports on the same PC, the connecting cable can be tested with 'Other End'.
Fuzzy scanning is a work in progress, but have helped with devices with no documentation; leave it running until some responses have a pattern to work from.
Mostly fuzzy is not needed, just send the default NewLine, and see which port settings allow results.
MODBUS scanning uses my own very old MB library, but integration in CS2 is not yet finished, and I only have one simple device to test against. And it needs wiring up.
Should not be needed.
Check that backups can be succesfully restored or verify two copies of the same folders are the same.
Files are compared by pathname and SHA256 hash. Result can be copied to fex a spreadsheet.
If checking restoring from fex tape there may not be disk space free for the entire restore. In that case use the options Watch and Delete on a temp folder and restore to there as shown.
This application had not been modified since 2009-12.
A quick one; most was in SharedBattery to debug battery status that gets a strange pseudo bitfield from WIN32, but PM has general uses:
It shows estimated runtimes all the time (runtime on full charge is stored, then used when Windows does not provide a current value), logs history and audibly notifies on powerline change and when charging stops.
If power status is needed in a script, see hWaitFor .
Code1.png)
Code2.png)
Code3.png)
Quickly add some HTML decoration. More options will be added as needed.
Also converts fex NewLine to <br> and < to < .
Use "To <pre>" to escape content for <pre> segments, fex like the "CMD screens" on this page.
HTMLContentIndex - 2026 - Henning Olsen - Release build: 2026-04-02T09:58:14Z
Input is a HTML file, where all headers <h1> to <h6> are extracted to a nested <ul> list.
Input example <h2>, properties are optional:
<h2 id="WhatAndWhy" data-hxo-desc="Really, why?">What and why.</h2>
Output:
<ul>
<li><a href="#WhatAndWhy">What and why.</a><br> Really, why?</li>
<ul>
Note: This is a simple tool; it is strict, only uses UTF-8 and is tested on simple HTML.
With problems, at least check your source with the browsers View Source, or better see one of:
https://firefox-source-docs.mozilla.org/devtools-user/validators/index.html
Arguments:
"Infile:PathName"
"OutFile:PathName"
WriteEnvelope - <!DOCTYPE html><html> BlahBlah </html>
WriteAnchor - Links to #id
"PrependAnchor:Content.html" - Use if Index is not embedded in content file. Use ReplaceText.exe for embedding.
WriteDesc - Writes data-hxo-desc after entry.
"PrependDesc:<br> " - Default shown. Prepend to description.
"AppendDesc:" - Default blank. Append to description. Fex add <small> and </small> around description.
Create an index of headings in a HTML file.
Example (also try View Source) from current page and:
HTMLContentIndex.exe InFile:HenningsSW.html OutFile:ContentIndex.html WriteEnvelope WriteAnchor PrependAnchor:HenningsSW.html WriteDesc.
BaseHieroglyphs replaces Base64 chars with chars starting at 77824, BaseSmileys at 128512 and BaseRunes at 5792.
Yes, a few are not listed on Binary-to-text_encoding .
PDF-fjant combines any number of PDFs, ignoring not-allowed-flags and saves them as one.
I dislike PDF for a number of reasons. It is properitary and overly complex. So you have to spend money and learning to get information into and out of the format. Resources that cannot be re-used with other formats. And viewing a PDF onscreen is less than ideal, as it never fits my screen. Just use HTML.
PDF-fjant (UI is also in danish) quickly happened, when one day I got a parts catalogue, where each of hundreds pages was presented in a website as separate PDFs. And the next day someone came in with ExpensiveDeviceManual.pdf that would not print to paper (laptops and tablets were expensive then) because of a flag set in the docoument. I was already looking into PDFSharp 
for a work request, that happily ended up not using PDF.
Not super useful today (it was for some years from 2009), as often newer PDFs have properties, that the gratis version of the PDFSharp library does not support. And I guess even the paid versions of tools struggle to keep up with new 'enhancements' from Adobe. I rarely work with PDFs, but every few years I use PDF-fjant, so I keep it around, and only rebuilt it for .NET 4.8.1. Writing this took longer.
Touch - Henning Olsen - Adjust file and folder timestamps.
Release build: 1.0.BETA.43 - 2026-06-19T15:57:42Z
File:PathName - More than one can be given.
Folder:PathName - More than one can be given.
InFolder:PathName - Find in this folder. More than one can be given.
PathPattern:* - Path must contain this fex: *\temp\output\* .
SubFolders - Include subfolders in InFolder.
FilePattern:* - Set on match. Default *, set blank for none.
FolderPattern: - Set on match. Default none.
ListOnly - Make no changes, only list selected (before SkipAlready).
NoList - Do not list files or folders on console.
Field:CWA - Set Created - Write - Accessed field(s). Default all.
From:PathName - Copy fields from file or folder.
DT:DateTime -
TOD:TimeOfDay
OffsetNow:Offset - Offset from now.
OffsetNext:Offset - Offset each consecutive file time. Works with From, DT TOD and OffsetNow.
OffsetFile:Offset - Offset existing file or folder time.
Reset: - Resets down to: second, minute, hour, week, month or year.
FromNewest - Sets Write on Folder from newest content. Uses FolderPattern:* if none.
Random:Offset - Make settime random +- with this Offset.
Also works with Interval and Compress.
Compress times between Start and End:
Oldest file or folder is set to Start, newest to End and
the rest spread relative to their time.
Works on all content in all InFolders as one!
StartDT:DateTime
EndDT:DateTime
StartTOD:TimeOfDay - Ignores date.
EndTOD:TimeOfDay - Ignores date.
StartDOW:WeekdayNumber - Monday is 1. Ignores TOD.
EndDOW:WeekdayNumber - Sunday is 7. Ignores TOD.
SkipAlready - Skip file or folder if it is already in the target interval.
Notes:
The same argument later on the line wins.
If two functions are needed fex DOW and TOD, run Touch twice.
Some functions are mutually exclusive with undefined results.
Argument starting with ' is ignored.
About patterns, see help-? in hSearch.exe.
If the Accessed field is OS controlled, it can be hard to set. See:
fsutil behavior set/query disablelastaccess /?
Example DateTime: 1999-02-25T19:12:21.25 or partial fex 13:13 or 2020-01-01. Partial time is today.
Timezone is assumed local, but offset from UTC can be added to the end fex +8 or -4. Use Z for UTC.
Example TimeOfDay: 19:12:21.25 or partial fex 13:13.
Example Offsets: 22.15:44:03.45 or -22.15:44:03.45 or partial fex 19:45.
Sets timestamps (Created, Written and/or Accessed) on files and folders, either directly or from criteria such as date, time of day or day of week. The compression of time could be useful (😇) in some BigCorp that deletes files after a year or two, but you need to keep documentation like source code or machine drawings a bit longer. Random can be used to make the changes look more natural (the three timestams get their own random offset), or fex to trigger file transfers.
Small fun facts: I did not come up with the name, it has been used for similar tools for decades. I happen to have been using:

Makes
Youtube 
subscriptions easily available for your RSS feed reader. Input is the CSV file obtained from
Google Takeout 
(see Help) and output is an
OPML
file.
Why? I often overlook notifcations, and the current notification system often falls over whith more than 20-30 pending and just skips some for no apparent reason. And I like to keep up without manual clicking. Same as any other website; no RSS means I will not be a regular visitor.
If you do not have a Youtube account or only add a few subscriptions, an alternate method is:
On a channel page, click More on the description. Click 'Share Channel' and 'Copy Channel ID'. Append ChannelID to https://www.youtube.com/feeds/videos.xml?channel_id=ChannelID, fex https://www.youtube.com/feeds/videos.xml?channel_id=UCk122TftdOJJAqLG0qS1J0g and use that for your feed reader.
For other methods see
Open RSS 
, a service that is also useful for other sites and feeds. Especially sites with no 'native' feeds. "Open RSS offers feeds that are a much healthier alternative to the intrusive, algorithmic feeds on websites that harm and manipulate us. Our service continues to generate thousands of feeds, and we won't stop until every website has one. With RSS feeds, we can all finally follow web content on our terms, using feeds that only we control."

Had forgotten about this, until it was missing on a new machine, as it was not in the current deployment. Originally from march 2006 AFAICT.
