A file shredder, also known as a virtual or digital shredder, is a program designed to render computer-based files unreadable, just as a conventional shredder makes physical documents unreadable.

How does file shredder work?

File shredders work by overwriting the file first before carrying out the actual delete. One of the most basic methods is to completely overwrite the file with bit values of zero. If someone was to look at the raw data after this all they would see are values of zero instead of the original contents of the file.
