Sure Delete is a file shredder which lets you remove all traces of any sensitive files and folders from your hard disk beyond all hope of recovery. Sure Delete includes a user-selectable level of security, logging capability, and the ability to clean your hard disk to ensure that files that were not removed cannot be recovered either.
Donate ware.
File-Saver which can recover deleted files also has file shredder. Fairly cheap at the price if you want to be sure the file(s) are deleted.
