How about a shred selection option by a mouse right click?
I was just thinking about something along these lines. Except, my idea was to give CCleaner a right-click option to securely clean the files that are "too big to fit in recycle bin" and would normally be cleaned without any security passes from Windows.
But a Shred option from another free program does sound like it could be dandy, and easily turned off from CCleaner's tool that's easy-to-use!
It's been requested before, and along with you guys I've also wanted that feature for several years myself - however it would be crucial for it to have shell integration via right clicking, versus being stuck to what we current have of deleting stuff to the Recycle Bin for it to be securely dispatched.
