Very good app in finding duplicate pictures. Picture Edition is able to find visually similar pictures of different file sizes that was not to be found in the standard dupeguru.

I am a photographer, and was becoming overwhelmed with the number of images I had across multiple folders with various names and needed help. Based on the other reviews found here, I decided to try dupeGuru. I am VERY HAPPY! First, I learned that I had almost 42,000 images in my various photo folders, and after a 4 hour grind through all of them, the Guru told me that 2400 of them were duplicates. I found the interface very easy to use, and efficiently cleaned up my folders and files. Thank you!

I am a Photographer so naturally I have a lot of photos. I have a portable hard drive and I keep dragging photos over to it, and not paying attention to if it was a duplicate. DupeGuru PE works great for getting the duplicate photo off of my hard drive.

DupeGuru PE is a little slow, but I expected it to take awhile, because I have so many photos.

I tried some other duplicate finding apps, and I like DupeGuru PE more than the others. The main reason I like more than the others is you can not delete the original photo. The other apps I tried you could delete the original photo if you were not paying attention.

Great for a free software. Did what I wanted (check approx. 40k pictures in several folders knowing that there are about 50% dupes). Takes its time and the UI is a bit spooky, but simply works.

Cannot review yet (or pay fairly), because:

After waiting very long, scanning 28k+ of 30k photos the process was aborted: reason: checked progress, hovered mouse over pic in finder, forgot to click, pressed space bar to do a quick view... ABORTED

DGPE aborts the process, because it treats space bar as an enter key to CANCEL the process. No warning, nothing, nada...

Hours of waiting gone down the drain...

Please developer...

You're right, that's pretty bad. Sorry about that waste of time.

I'll remove the focus on the cancel button for the next release.

That being said, a big part of the scanning time is taken by picture analysis, which is cached in a database, so if you start a scan again, it won't take as long.


Thx, for the quick response.

And for the hopeful last comment. Will try it tonight.

Everything Arras said earlier (below), I second. The only thing I can add is that I usually scan at 90 percent, and I have yet to see a false positive out of two scans of over 25'000 images each. As far as false negatives, I can't know, of course, but I can only hope those are as rare.

As Arras mentioned, though, it does take time. This is not unique to dupeGuru PE, though, as all duplicate image scanners will be time-bound. (For the mathematically inclined, it's O(n^2) -- each picture you add must be compared against all the others.)

Thanks for making this clear: the time necessary increases with the *square* of the number of pictures to be compared. So obviously, it does take time if you want to clean huge galleries.

But the results are convincing to me: duplicates of different pixel size or compression level, which cannot be found by exact duplicate checkers, are retrieved very reliably, and - up to some 100,000 items - within a quite reasonable amount of time.

Still not bug free for my 25000 photos archive. For smaller archives I love this app.

Thanks for your comment. iPhoto sometimes produce invalid XML in its album data. I try to work around these invalid XMLs as I see them, but I can't work-around a file I haven't seen yet.

Can you please contact support@hardcoded.net so we can fix this?
