File Locking in Android

Locking is available for both files and folders. It indicates that you are actively editing that file or folder and don't want others to edit it as well.

When a file or folder is locked in Android:

• A lock icon overlays the file or folder:
  
• The owner of the lock has full access to that file or folder and can modify it.
• Admins can always override a lock using the admin panel.
• A lock can be set up to prevent the locked file from being read. In that case other users cannot download or view the locked file or folder.

• The following table shows the behavior depending on the type of lock.

  Lock type	Access by lock owner	Access by others
  Read permitted	Full access to the file is available. Share/Sync/Edit/Delete allowed.	Only read is allowed. No modification is allowed.
  Read not permitted	Full access to the file is available. Share/Sync/Edit/Delete allowed.	No access is provided. All access using all clients is blocked.
