A tool to find duplicate files on your computer.


dupeGuru is a 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.

  • dupeGuru is efficient. Find your duplicate files in minutes, thanks to its quick fuzzy matching algorithm. dupeGuru not only finds filenames that are the same, but it also finds similar filenames.
  • dupeGuru is customizable. You can tweak its matching engine to find exactly the kind of duplicates you want to find. The Preference page of the help file lists all the scanning engine settings you can change.
  • dupeGuru is safe. Its engine has been especially designed with safety in mind. Its reference directory system as well as its grouping system prevent you from deleting files you didn't mean to delete.
  • Do whatever you want with your duplicates. Not only can you delete duplicates files dupeGuru finds, but you can also move or copy them elsewhere. You can also easily weed the bad duplicates out, thanks to the Power Marker.

There are MUCH better choices to find duplicate files on your drives. The best include "TidyUp!" and "Spring Cleaning 10". My personal choice is "FileBuddy9" the only application that can search through invisible files and system files. Dupe Guru is virtually worthless. The current version took over an HOUR, as opposed to several minutes with the others listed above. To be avoided.

Looks like this great tool have been neglected for a while... :-( v4.0.3 that's linked here is ok (DL from the old dev) but I had a hard time opening the one from the new dev (which appears to be identical, in the end...) At the present time, there's a v4.0.4 but only for Windows and Linux...

This app solved large number of problems for me. This is the best tool to find duplicates by their file names. Others do with checksum searches. For files stored outside of the Spotlight, none of them work.

Although not the best interface for Pictures duplicate comparison — you have to use QuickLook — this has now totally stopped working for me on several pictures/movies folders. I just get a crash that I’m supposed to post to GitHub, but it’s already there. I get the feeling the develop is not working on fixing this daily. Time to move on perhaps. Anyone got any others they prefer?

I have just used this on Sierra 10.12.4 and it seems to work just fine. Pretty good for free!

Simple use. Just drag a folder in the window and dupeguru finds duplicates, even with not exactly the same names. It is then easy to eliminate the duplicates (or nearly duplicates) you want to remove, within the application. It shows the percentage of difference between files and their creation/modification date to simplify the choice for removing one of the two (or more) duplicate files. Great app !
