Free Space Shredder option

As someone who uses CCleaner primarily to have a one-click way of deleting all the cookies and temporary internet files on my computer, i think it would be nice if there was (in addition to the registry cleaner option) a sort of free-space shredder.

With such a quality cleaner, i think a free space shredder (or even a file shredder) fits the bill and would make CCleaner all the more do-it-all.

Plus, it always troubles me that hidden somewhere in the "free space" in my computer is a cookie with one of my saved passwords to an online banking account --- as i'm sure most know, "deleted" files aren't ever really deleted per se; they're just put into the "space-that-will-eventually-be-overwritten-with-new-data"....and i don't like waiting for that "eventually" to happen.

Okay, well i've rambled on about it enough.

Does anyone else think a free space shredder would be a good option in CCleaner?

YES! I got one on another program called ncleaner, but it won't work on my PC for some reason. Though I think the free space shredder would fir better with Recuva wouldn't it?
