I have excluded from this comparison those tools which could not be readily installed on my macbook (eg.
From there I downloaded and installed all free/open source command line tools. Wikipedia has a pretty complete list of duplicate file finders. So I decided to compare the speed of most of them. And no easy way to find which one is best. I quickly realized that there are far too many tools which have been written for this task. The obvious choice was to search for a command line tool. One could try with iPhoto or some other graphical interface, but the approach is simply too slow for a large library (over 100GB). Now that I have reached the limits of my hard drive space, I figured the best thing to do was to remove some duplicate pictures. Too afraid of losing family memories, often I end up downloading pictures from my phone multiple times, “just in case”. I do try to save everything in one place and have backups, but it is difficult to keep track of it. Why a duplicate file finder?Īs a parent, my picture collection has mushroomed in size. Other python and perl based solution did also very well, often better than their C/C++ colleagues.

Amongst the free tools that were correct in identifying all duplicates in my test, dupd was the fastest. And because I could not choose which duplicate finder to try, I have decided to test them all. I needed to clean up duplicates photos from my personal library.
