BC Wipe
Need to remove sensitive data from your computer? Many people don't realize that deleting a file doesn't actually erase it; it just removes references to its location on your system. The file can usually be restored with a good disk tool. When you have to make sure all traces of a file are really gone, you need a program like BCWipe. This freeware tool hooks into the Explorer right-click context menu to enable you to get rid of data permanently. Files and folders can be wiped clean and deleted with just a few clicks. Two main modes of wiping are provided: Normal standard wiping (in which you may define the number of passes) and U.S. Department of Defense seven-pass, extended-character, rotation wiping. BCWipe also lets you clean all free space on your hard drive(s), shred the contents of the Windows swap file, and view a file before you remove it.
