From ProCypher Software:
Procypher - File Eraser and Hard Drive Wiping Software. Securely and permanently deletes your computer files of any type and size fast.
It's fast, powerful, and easy to use. This is our best selling software program and is used by satisfied customers from all over the world. If you want the most powerful and sophisticated, yet easy to use file wiping application available - this is it.
When you delete files using your operating system's delete function it does not actually remove those files and their data from your hard drive, it just makes the space those files take up available for other files to use in the future - it does not truly 'delete' (erase or wipe) the data from your hard drive and these 'deleted' files can be recovered using special software.
Procypher Eraser Pro software application does truly 'delete' your files off your hard drives and all other forms of magnetic storage media including external hard drives and floppy disks by repeatedly wiping your drives magnetic media many times over with algorithms that exceed the United States Department of Defense DOD 5220.22-M specifications for permanently removing data from magnetic storage media (hard drives, floppy disks).
You can be assured that the files and the data they contain that are removed from your computer using Procypher Eraser can never be recovered by any known means, even the file name is erased beyond recovery.
Version 2.5 includes Windows Vista and Windows 7 compatibility and speed improvements.
