Even after I close the Cryptomator vault, the files still show up in my file explorer quick access. Though most files like word documents can’t be opened, pictures still can. The name and thumbnails of files also are shown in quick access after vault lock. Is this normal? Is there a way to fix this on my end?
Windows stores thumbnails in a cache that’s not inside the vault. Same for quick access filenames and path. That’s normal and leads to the behaviour you describe.
