If you think that when you delete a file, it is really gone from you PC, think again - all that happens is that Windows marks the space the file occupied as being available. This means that anyone with a program such as Restoration could probably recover them. Sure Delete not only deletes the file, but overwrites the data, making it essentially unrecoverable. There are three deletion methods: a quick wipe (which overwrites the file 4 times, a Department of Defense method (which overwrites the file 7 times with random data), and a Super Secure mode which overwrites it an impressive 24 times. Obviously, not every single file requires to undergo this extreme form of deletion, but if you might have some that do. If so, this utility is really useful!
