Another freebie for Windows 8....

This one adds more items to the right-click menu in Windows 8, according to how you configure it, and one of those items which I like very much is an industrial-strength shredder for destroying files you want gone forever. It has many other useful items as well, and it works on any Windows from XP onward,
including Windows 7 and Windows 8, both 32-bit and 64-bit. 

Here are the choices for various shredding operations offered by the program.
