Over the years, my photo library has been managed by numerous apps (Picasso, iPhoto, gthumb, etc) and stored in multiple cloud and local drives. As a result I have a number of duplicates that I'd like to eliminate for easier organization. Is there a FOSS app that would assist with this task?
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 runs on Mac OS X and Linux.
dupeGuru is good with pictures. It has a special Picture mode that can scan pictures fuzzily, allowing you to find pictures that are similar, but not exactly the same
