Unlocker is a freeware app that will, well… “unlock” your files or folders from other processes so you can delete them.

Unlocker is an Windows Explorer extension allowing you with a simple right-click on a file or folder to get rid of error message such as error deleting file or folder, cannot delete folder: it’s being used by another person or program.
Helps delete locked files with error messages like:
- 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.
I used to have such issues with movie files (avi/mpeg and so on) and with trillian generated files (received files via MSN or ICQ). Now I can delete, rename or move the whole stuff without any effort.
Highly recommended.
