Visual Interface for the Windows 10 Compact Function

What is the Windows 10 compact.exe function? It's a commandlet with a collection of new algorithms introduced in Windows 10 that allow you to transparently compress games, programs and other folders with virtually no performance loss.

Transparently? What does that mean? Transparent compression means that files can still be used normally on the computer as if nothing had happened - they don't get repackaged like Zip and Rar files do.

How is this different from the built-in compression in older versions of Windows? This is similar to the NTFS-LZNT1 compression built-in to Windows (Right click > Properties > Compress to save space) however the newer algorithms introduced in Windows 10 are far superior, resulting in greater compression ratios with almost no performance impact.Those with older HDDs may even see a decent performance gain in the form of reduced loading times as the smaller files means it takes less time to read programs and games into RAM.

Uses
Use this tool to:

• Reduce the size of games (e.g. Fortnite: 18.8GB > 10.2GB)
• Reduce the size of programs (e.g. Adobe Photoshop: 1.71GB > 886MB)
• Compress any other folder on your computer

Extra Features

• Visual feedback on compression progress and statistics
• Configurable list of poorly-compressed filetypes that can be skipped.
• Online integration with community-sourced

  to get compression estimates and analyses
• Integration into Windows Explorer context menus for easier use.
• Drag-and-drop functionality
• Analyze the status of existing folders
• Shutdown/restart/sleep on completion.

Options
By default, the program runs Compact with the XPRESS8K algorithm active. This provides a good balance between compression speed and size reduction. The default that Windows uses is XPRESS4K which is faster but compresses less. The options available are:

• XPRESS4K: Fastest, but weakest
• XPRESS8K: Reasonable balance between speed and compression
• XPRESS16K: Slower, but stronger
• LZX: Slowest, but strongest - note it has a higher overhead, so use it on programs/games only if your CPU is reasonably strong or the program/game is older.

Here's the output tests for Adobe Photoshop:
