software's that will permanently delete files?

[SKELO]

Does anyone know any trusted and working software's that will permanently delete files on a hard drive?(overwrite file space on the hard drive so the original file is no longer recoverable)

There's also a program called unlocker. It will unlock files and if there's no lock on it, it will delete them.

CCleaner will do that also.
