When you've got a sensitive paper document to dispose of, you don't just throw it in the trash—you shred it. Why should your computer documents be any different? Deleting a file on your system doesn't really delete it, and it's not that big of a challenge to bring it back. That's true whether you just deleted that file, or possibly even if it was deleted a long time ago. To really get rid of that file, you need something stronger.

FileShredder is a free app that can help you to really get rid of that deleted file. Rather than just telling Windows that the space formerly occupied by your file can be re-used, this tool overwrites that file multiple times with binary data. Think of it like this: write a word on a sheet of paper with a pencil. Now erase it. You can probably still see it. Now draw a line through it. Still there. Okay, now draw multiple lines through it—horizontal, vertical, diagonal. Now draw a series of curlicues through it, Repeat. After a while, you're going to have a tough time identifying that original word. That's how FileShredder works. There are several different shredding algorithms to choose from, so you're probably going to be able to do a pretty thorough job of killing that file you want to get rid of.

FileShredder is a free Windows tool. It runs under Windows NT / 2000 and later.
