Lost Hard Drive space with Clone DVD

Let me start by stating that C: CloneDVDTemp was/ is empty
I was trying to copy a DVD that was really scratched and Clone DVD had an error about half way through coping. No suprise, untill I found out that it had ate some hard drive, some very needed hard drive. I can not find what it did or created to use about 2 gigs. I used the find function and chose files created today but that turned up nothing useful. Can someone please point me in the right direction here? Does it have another temp file or folder somewhere I can delete? Thanks guys.

@ Johnny D,

Look for a VIDEO_TS Folder and/or files ending in .VOB, .IFO, and .BUP

Best Regards,
