Original title: Android: Deleting .lck files So S3Drive crashed syncing my monstrosity of a folder. Just restart right? Not quite, there's a lock now. Deleting and re-creating the sync entry does NOT work. Lock file stays. I suppose uninstalling/reinstalling the app might work, but that's cumbersome. I have a rooted phone so I just delete it, but there's a lot of unrooted phones out there.
