Hi. I have beeen using CCleaner for about 6 months now. It's amazing. I've never had a problem with any of its features. I've recomended it to everyone I know, I I install it on every computer I see. The other day, I was looking at similar (but inferior) disk cleaners, and noticed that a few had a feature which scanned the hard disk for duplictae files and then deleted the duplicates. I think this would be another outstanding feature to add to CCleaner. It could be one of the checkboxes or something. Thanks for the time.
