K18 File Compressor

K18 File Compressor is a Windows storage optimization app that uses NTFS LZX compression to reduce the disk space used by games, videos, and audio files without changing their original formats. It automatically discovers supported files, estimates potential savings, displays actual savings, identifies possible DirectStorage and anti-cheat compatibility concerns, and can recompress files after updates. A dark, easy-to-use interface provides library management, activity tracking, restoration, and secure application updates, this app can sit in the background and watch for file updates then recompress when all file activity stops.
