Use a great deal of caution before deleting any files that appear to be duplicates. Many programs have the same file in their folders as they load their own copy. What appears to be a true duplicate in most cases is not. In my opinion, there is little use for a program that finds "duplicate" files. Many inexperienced users delete necessary files and get in to a great deal of trouble. Unless you are intimately familiar with the dups, do not delete them.
