Unlocker helps you access files locked by the Windows OS. Unlocker Assistant stays in your system tray bar and automatically launches Unlocker if you are trying to delete/rename/move a file that is locked.

Locked files can come in in various ways:

• Cannot delete file: Access is denied
• There has been a sharing violation.
• The source or destination file may be in use.
• The file is in use by another program or user.
• Make sure the disk is not full or write-protected and that the file is not currently in use.
