Changes

NEW Added Scheduler

  • Adds the ability to schedule background compression of watched folders, with the following choices:
    • When system is idle (existing functionality)
    • On Schedule
    • On Schedule if system is also idle (for example you want to run it at 6pm every day, but only if you're not actively using the computer)
  • If the Scheduler is running and you wish to cancel it, you can do so from the Watcher tab as below
  • Note: Scheduler will only run if the computer is already on and CompactGUI is running.

NEW Manual compression of all watched folders

  • You can now compress all watched folders manually from the Watcher tab
  • Any scheduled background compressions can also be cancelled from this tab when they are running too.

NEW Logging
Hopefully this will make error reporting easier - logs are now generated and saved to %IridiumIO%/CompactGUI. If you run into issues with CompactGUI, please share these logs when creating an issue! Hopefully they catch the reason for any crashes or problems.

TWEAKS UI Updates

  • Improved Compression Mode option buttons and layout of main area of CompactGUI
    • the hover effect can be disabled in settings if you prefer to always see more details
  • Tweaked results view (not sure if this looks better or not - probably will change again later)
  • Adjusted Watcher page layout - now includes button to compress all watched folders on command
  • Changes to base background colour and image use


Fixes

  • Fixed several memory leaks
  • Major performance improvements in several areas and reduced overall memory usage
  • Fixed a crash that could occur when opening the skiplist
  • Fixed the watcher list nuking itself if a monitored folder is deleted [Suggestion] Back up Watcher list #546
  • Fixed instances where the background watcher simply doesn't do anything
  • Fixed the compression buttons showing the wrong estimates Possibly showing incorrect estimated saving from database #543
  • Fixed spamming disk writes when the user changes settings (previously every change in the settings menu would immediately write the new settings file to disk - now this is debounced)

Installation

Binaries

CompactGUI.exe (10MB): Smaller size, but requires .NET 9 Runtime to be installed
CompactGUI.mono.exe (64MB): Fully self-contained and embeds the necessary .NET 9 libraries

WinGet

winget install CompactGUI

Note

Installing from WinGet automatically installs .NET 9 if required, however it can often take a few days for new releases to become available.

But if I compress a Steam game, is it still playable or does it have to be uncompressed before being launched?

It is playable. Windows uncompresses it automatically, on the fly.

if windows uncompresses a game on launch, then would that mean when you launch a game it reverts back to its normal size?

Nope, the decompression happens in memory when the data is loaded, it only reverts to its original size if you change the file.

When does this software support windows compression if enabled? since version 4 it doesn't support it, so I can't recompress files anymore when windows compression is enabled.

Once again I am here to ask if you can re-add this type of feature when hovering over it:

Overall though, I LOVE the new look. Should I make this as a Issue though?
