CompactGUI

Reduce the space taken up by games and programs on disk by using native Windows APIs

CompactGUI transparently compresses your games and programs reducing the space they use without affecting their functionality. It works directly with the Win32 API to achieve the same thing as the native compact.exe command-line tool available from Windows 10 onwards.

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. You can still browse, launch games and programs exactly as you did before.

Uses

• Use this tool to compress folders while still being able to use/run them normally:
• Reduce the size of games (e.g. ARK-Survival Evolved: 169 GB > 91.2 GB)
• Reduce the size of programs (e.g. Adobe Photoshop: 1.71 GB > 886 MB)
• 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 database to get compression estimates
• Steam game results can be submitted to the online database from within CompactGUI
• Integration into Windows Explorer context menus for easier use.
• Analyze the status of existing folders
• Background Watcher - keeps track of folders and monitors them for changes (e.g. Steam game updates) and automatically keeps them compressed in the background.
