Where Does Fusion 360 Store Cache and Files?
Fusion 360 cloud sync cache and exported archive folders on Windows and macOS for CAD design file use.
Last updated
Fusion 360 keeps designs in the cloud with a local cache for speed. Windows caches under %LOCALAPPDATA%\Autodesk\Autodesk Fusion 360 with versioned webdeploy folders. macOS mirrors this under ~/Library/Application Support/Autodesk.
Portable copies are explicit exports as .f3d archives wherever saved. The cache only mirrors recently opened designs. Back up exported archives, not the cache, for moves. Cache paths shift with each webdeploy update. Offline mode opens cached designs without internet. Version history restores older design states.
