Works pretty well. Filters Need a Tweak

I downloaded and tried the app which worked pretty well. It took a minute to play with the interface to understand what I was doing, then it was pretty straight forward. So not bad. I used it to find dupes in my folders and then my library. The interface allows a quick comparison of duplicates along with the data of the selected photo making the review a little easier. There are preferences for filter selections which are set up pretty well, save for the one I wanted to change. It defaults to keeping the lastest copy of the photo. I wanted to keep the earliest. Unchecking the filter didn’t do that. It continued to choose the latest. Fortunately, you can command-click on multiple photos and right click on the group to mass unmark and mark to reverse this. I didn’t have a large group of photos that I was working with, but if I did, this could have become tedious. Other than that, it worked well and had a nice set of directions that popped up at the end to help locate the duplicates in Photos that were isolated for deletion.

Great, from someone who is pretty critical

I’m a software engineer myself, so I’m pretty picky about my applications. (Yeah, I know that sounds elitist, but I’m trying to make a point…).

I don’t often rate apps, since I don’t have full confidence in the rating process — lots of ‘fixed’ reviews. Anyhow, when I do come across a great app, though, I need to talk it up. This one’s the latter. It does what it says it does, is super fast, light weight and easy to use.

If I need to make a critique, it’s that I HATE popups on load, which tell me about BETTER software I can buy. It pretty much says “Hey, sucker — you just wasted your time searching for and downloading a good looking app, because here’s something better!” Sort of dings my ego, I s’pose. Insead, might I suggest that you put a link in the menu with a flow such as: “Like this app? Check out our others!” Since I do like your app, I’ll gladly check out your others.

Anyhow, for those looking for a basic de-duper, this one is A-OK.

To those whining about the strange process to delete dupes from Mac Photos/iPhoto, I can attest that this is a minor inconvenience, necessary due to the complex way Apple designed that app and its folder structure. The fact that this app can process an i/Photo/s library is FANTASTIC, and totally worth the extra 60 seconds it takes to read the screen and do what it tells you.

Great job, Systweak Software!

Lightning fast compared to other duplicate finders

I have over 400k photos in my library with many, many duplicates from years of upgrading systems and not properly copying the pics over. I have tried many other apps to find duplicates in my libraries and none have worked this fast! I love this app! Sure, I would love to be able to fine tune the filter to further expand my duplicate search to include eliminating thumbnails, as well as similar photos taken within seconds of each other…I imagine/hope these kinds of tweaks might come in the future? But in the meantime, this app has immediately helped me successfully wipe out 89k duplicates in literally 30 minutes or so in 2 libraries! Only 7 more to go… Before, it would have meant that my system would have been tied up for days & god help me if my system crashed!
