Unlocker: Program You May be Looking for with Your Whole Life Time
Ever had such an annoying message given by Windows?

It has many other flavors:
* 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.
Unlocker is an explorer extension that allows you with a simple right-click of the mouse on a file or folder to get rid of this error message!
