BE CAREFUL WITH THIS APPLICATION! It is a file shredder, as the name implies and if used incorrectly, it can permanently destroy files on your hard drive! I've built in lots of bells and whistles and warnings, so it should be difficult (to say the least) to blow something up and not know it! The Shredder, despite its risky nature, is a useful program that can increase your personal security by eliminating sensitive files. This program was experimental and intended to lay the foundation for file shredding techniques I have since used in many other programs.
