There are a few useful tips about how file locking works: 1) A locked file can only be unlocked by the user who locked it. 2) A locked file cannot be modified, moved, renamed or deleted by other users. But other users can still move, delete or rename the parent folder of a locked file. The purpose of file locking is mainly to prevent concurrent editing. 3) When a locked file's parent folder is renamed or moved inside the same library, it remains locked after the operation.
