Customer Reviews

Very pleased

I want to move to a new computer by the end of the year, so this seemed like a good time to cleanup my photos. My computer says I have over 600,000 jpg files, mostly in iPhoto and Photo libraries. In the past I have tried other cleanup apps, but they were slow and did not give a clear picture of the results. PhotoSweeper is well laid out giving you a good visual display of what photos are considered duplicates. There are many options to fine tune how a duplicate is determined. I am still learning how to take advantage of all the options, but even just using the defaults I was finding duplicates within minutes of installing the software.

One suggestion, if you are expecting a lot of duplicates, work with small groups. My first try was to compre 75,000 photos. PhotoSweeper found ~2000 duplicates within about 15 minutes. It was going to take couple of hours to convince myself that I was deleting the right photo and currently there is no way to save your comparisons, if you want to take a break from reviewing duplicates. I’m sure in time I will be more comfortable just deleting the duplicates without review.

Finally, the support team has been FANTASTIC. I have emailed them a few times as I ws getting started. Their responses were right on target and extremely timely (usually less than 2 hrs and sometimes in minutes).

As I said, Very pleased.

Great software and support

I bought this for cleaning up my Photos library on my external hard drive. However I couldn’t get the library to read. I emailed the Overmacs support team, got a very fast response with some tips I should try. One suggestion was to repair my Photo library. I did this, then restarted Photosweeper and viola it worked. I was able to scan my 70,000+ library and it found over 3500 duplicates. I reviewed a bunch, and deleted them. The software is super easy to use and very useful. I would never do it otherwise as it would be so time consuming. I’m a happy camper, just trying to clean things up. Thanks for the great software and especially the support team for excellent communication.

Everything that I wanted

With only a few minutes of time, this app visually compared the 29,000 photos in my Photos library, plus also compared 1,000’s of photos that are in other photo libraries and in directory trees on my computer. It used many criteria to choose which similar photo to keep, and which duplicates to remove. The criteria can be adjusted easily for your own purposes. It only allocated around 1GB or RAM to do the job because it is well-deslgned. The default criteria is pretty good: it will prefer photos that are favorites or have tags, etc.

I am extremely pleased with PhotoSweeper and recommend it to novice and advanced users.
