On most PCs and servers - and certainly on any network - you will find more file duplicates than you can handle. One place to start is finding the duplicates that are taking up most storage space. This is very easy - from the welcome page click on "Get rid of files that are duplicated" and choose "Large duplicated files". All sets of duplicated files that are taking up more than 10MB will be quickly listed. Use the "Custom Search" options to refine your results.
