How to lock or unlock a Dropbox file

File locking is a feature available to Dropbox Business and Professional users that prevents a file from being edited. This allows teams and collaborators to coordinate who is editing a file and avoid conflicted copies.

Once a file is locked, anyone with access to the file can still view, comment on, and share a link to the file. Only the person who locked the file can edit and unlock the file. 

If you need to edit a locked file, you can request that the file be unlocked by clicking Ask to Unlock in the window that appears when you attempt to open the file. Or, you can make a copy of the locked file—however, any changes made to the copy will not be reflected in the original file once it’s unlocked.

Note: Only files in shared folders can be locked.

To lock or unlock a file using the Dropbox desktop app:

  1. Open the Dropbox folder on your computer.
  2. Right-click the file you’d like to lock or unlock.
  3. Click Lock Editing or Unlock Editing.

  2. Click All files in the left sidebar.
