CS-P04 · Dense world
Smaller games.
Nothing deleted.
ShrinkMyGamesAndFiles compresses installed Steam, Epic, GOG and Xbox libraries using Windows' own NTFS/WOF transparent compression. Games launch normally — Windows decompresses on read — and every byte of it is reversible. It is free: no licence key, no activation, no account.
How it decides
This is the whole product. Compression is planned per file, never applied uniformly — the engine is detected, each file is classified by how the game actually reads it, and real compressibility is measured by sampling before anything is touched.
Detecting engine…
A simulation of the real classifier — real marker files, real classes, real algorithms, plausible sizes. Not a screen recording.
See it running
A capture of a real library being scanned, planned and compressed — and the same drive afterwards, with the games still launching.

Recorded on a real library — no reconstructions.
What it does
Savings preview
Scan first and see the real number before committing to anything. Proof, not promises — the measurement happens before the work does.
Every launcher
Steam, Epic, GOG and Xbox libraries, across drives.
Play without extracting
Nothing is unpacked to play. Windows decompresses on read, so the game just launches.
Four compression levels
XPRESS 4K, 8K, 16K and LZX — chosen per file, not per library.
Video re-encoding
Quality-targeted 4K re-encoding through ffmpeg, with HDR preserved and the result measured rather than assumed.
Duplicate collapsing
Finds the same file living in several places.
Update detection
Notices when a game updates and re-plans the files that changed.
Always reversible
Uncompress any file, folder or whole library at any time. Nothing is ever deleted.
Activity log
Every file touched, with what was done to it and what it saved.
