Delete/Rename locked files in Windows with Unlocker

"Cannot delete File4.mp3: It is being used by another person or program".

You may have come across the above message quite a few times. This happens because Windows locks files or folders that are currently used by other applications or shared by other users.
In comes Unlocker! What is that?
Unlocker is a small freeware which will help take instant action when you encounter similar situations. Once installed, Unlocker will be available from the right-click context menu.

If you get a message when trying to delete or rename a locked Windows file or folder, just right-click the file and select Unlocker.
Unlocker will open a window displaying all the processes that are locking the file or folder. Select some of them and click Unlock.
You can now proceed with you task.
