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.

    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.

    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.
