Download Unlocker 1.8.6
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.
Of course I only compare here the unlocking features. Process Explorer and Take Control are very good programs featuring much more things than just unlocking folders. The goal of this list is not really to pretend Unlocker is better but instead to provide a list of all other alternative programs in case you have some difficulties with Unlocker.
