Freeraser - For when you really, really need to get rid of a file

The analogue world has shredders that chew up and spit out paper documents as a secure way of erasing the existence of a document beyond recovery. Burning is even more secure. But what about in the digital world?

Most folks don't realize that deleting a file on their computer doesn't erase it. All that does is tell the computer that it can use that space on the hard drive to store other stuff. It will eventually be overwritten, but even then it can be recovered for awhile yet.

This standalone app can be run from a thumb drive or from your own machine without installation. It places a temporary biohazard trash bin on your desktop, allowing you to drag and drop files that you really, really want to get rid of. You can specify that level of destruction you need. From the web site:

"# a fast destruction (standard 1-round filling of random data)
# a forced destruction (3 rounds of filling according to DoD 5220.22M standard)
# an ultimate destruction (35 rounds of filling with data according to Guttman algorithm)."
