Now that the program has been installed, Unlocker will have added a autorun entry to your registry to start the Unlocker Assistant when Windows starts. This background program stays resident and detects when you try to delete, copy, rename, or move a file that is in use.
When it detects one of these operations, it will automatically open up a Window in order to assist you in working with the file.
Example
With Unlocker installed, when you press the
OK button to exit the error, the Unlocker Assistant will automatically launch to help you delete the file.
From the
Dropdown Menu select
Delete and then click
OK 
What this does is delete the open file handles and then attempts to delete the file.
If Unlocker still has problems deleting the file after closing its file handles, it will ask you if you want to delete the file on reboot as shown below.
Choose
Yes and restart the computer to complete the process.
Unlocker is useful with the following errors:
- 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.
