Find Duplicate Files in MacOS

In the past I’ve used FSLint or even some BASH magic to find duplicate files but I have a huge archive of photos and videos, some of which were renamed during import, and some were accidentally imported more than once, or moved about. It’s somewhat chaotic

So I was very glad to find dupeGuru! It’s a powerful application for MacsOS and Linux that allows you to scan one directory or more for duplicate files. It can search by content, or match filenames. It has modes for music and pictures, but I’ve stuck with the standard search as I want to only look for files that are 100% the same.

It found several gigabytes of duplicates for me, and it has a useful feature that symlinks duplicates to their parent. Even though the dupes still exist, they’re not taking up any space.

The developer is looking for help to maintain the project. You can find more information and source code too on the dupeGuru GH page.
