dupeGuru is a free and open source tool to find duplicate files on your computer. It can scan either filenames or contents. The filename scan features a fuzzy matching algorithm that can find duplicate filenames even when they are not exactly the same.































Unlike Audio Comparer, dupeGuru is stable. In tag matching mode it displays more tags than Audio Comparer (or any other audio comparison tool I have tried). Unfortunately, content matching is separate from tag matching and the content matching criteria are neither clear nor adjustable.
