When you delete a file ordinarily, it isn't actually removed. Contents
of the deleted file continue to be stored on the disk and can be easily
recovered using any unerasing utility. BCWipe overwrites the file with
random data, making recovery impossible. It integrates into Windows
Explorer, so you can easily select and wipe any number of files, using
the normal one-pass wiping or the more secure seven-pass method. This
version of BCWipe introduces predefined DoD 5200.28-STD and Peter
Gutmann wiping schemes. The program can also be run from a command-line
prompt. If you're feeling adventurous, you can even create your own
wiping scheme to shred sensitive information on your computer.
