Where Does Fusion 360 Store Local Cache?
Fusion 360 local cache and offline files on Windows and macOS, with the cloud truth about designs.
Last updated
Fusion 360 is cloud-first: designs live in Autodesk projects while the local disk holds cache, login state and offline copies. The folders below are cache, not archives.
Exports are the real backup. Relying on cache folders for design safety misunderstands the storage model.
Where Fusion 360 stores this, by platform
%LOCALAPPDATA%\Autodesk\Autodesk Fusion 360
Cache and app state, not design archives. Clear with Fusion closed to fix sync and loading issues. Export designs from the data panel for real backups.
~/Library/Application Support/Autodesk/Autodesk Fusion 360
Same cache role. Use Go to Folder in Finder. Designs remain in the cloud account regardless.
Frequently asked questions
Where are my Fusion designs saved locally?
They live in your Autodesk cloud project, not on disk. The local folders hold cache and login state. Sign in on the new machine and designs sync down; offline-cached files need exporting first.
How do I clear the Fusion 360 cache?
Clear the local cache folders with Fusion closed. It forces fresh downloads of cloud data and fixes many stuck-loading and thumbnail issues. Uploaded designs are unaffected.
