GoKawiilUnofficial FUSE tool lets Linux users mount Proton Drive as a local folder
A developer has released an open-source, unofficial FUSE-based filesystem that mounts Proton Drive directly into the Linux file system. The tool lists files via Proton's metadata and downloads file content on demand rather than syncing everything upfront, with remote changes propagated through Proton's event feed and local writes buffered before upload. The project is not affiliated with or supported by Proton AG, and the creator describes it as early-stage software that has only been tested on one Proton Drive share.
