How to Clean GOG Galaxy Webcache & Installer Temp
Location & Quick Verdict
%ProgramData%\GOG.com\Galaxy\webcache
GOG Galaxy caches high-resolution game backgrounds, store assets, and offline installer manifests in ProgramData\GOG.com\Galaxy\webcache.
Why GOG Galaxy Webcache & Installer Temp Balloons After Game Patches & Season Updates
Modern PC game launchers, anti-cheat engines, and peripheral daemons write encrypted chunk depots, delta-patch staging archives, and Embedded Chromium (CEF) storefront assets directly into %ProgramData%\GOG.com\Galaxy\webcache. Whenever a download pauses, switches branches, or applies a major seasonal update, uncommitted delta chunks and superseded installer archives are frequently left orphaned on disk because launchers prioritize patch speed over post-install garbage collection.
Leaving 1.0 GB – 6.0 GB of stale depot chunks and session telemetry sitting on your primary NVMe SSD reduces free block headroom and slows down Steam/Epic/Riot delta-patching I/O. Purging GOG Galaxy Webcache & Installer Temp while no game update is actively downloading frees 1.0 GB – 6.0 GB immediately without touching installed game binaries, local save files, or controller/mouse macro profiles.
