WIndows 7 SP1 64-Bit
CCleaner v3.12.1572
I was running the Drive Wiper, for the first time ever. I've been a long term CCleaner user, and all else works, so I decided to just give it a whirl.
Issue is, during the Wipe, my computer started seriously lagging. I had to force shut down. Everything works now.
BUT. An extra 200GB or so of my HD is used up. Where are these files, so I can obliterate them?
And yes. Computer is clean.
