Check out http://www.easyduplicatefinder.com/  - it has tracked down all the identical demos, powerpoints etc all over my C drive in quite a short time. I haven’t let it do the deleting yet, but the finding is worth a lot to me (I can delete for myself once they’re found.) Three gig of duplicates and that’s without looking on the networked shares where I store things when I’m done!
