Recommended File Shredder
It really should be common knowledge that “deleting” a file does not really delete it. It simply flags the file as “deleted” by changing one small bit of information in the file name.
The file is still readily accessible through the use of an “undelete” utility until at some point in the future, that files location on the hard drive is overwritten.
Even then, there are “forensic” tools that can often reconstruct files even after they have been simply overwritten.
Therefore sometimes it is wise to “shred” files, so that they cannot be reconstructed. Shredding is a common name for a technique that overwrites the file numerous times in a manner that as been carefully developed to prevent that file from being reconstructed.
We recommend the Eraser secure file shredder utility, which is available *free of charge* at the authors web site:
