Really Struggles with Large Collections

This is a promising and robust problem, but it’s flawed. It sports an enormous number of options, as compared to some other duplicate-photo finders. That said, it hasn’t really worked for me. After numerous passes, even with extremely liberarlly settings applied, PhotoSweeper consistently misses duplicate photos that are clearly all-but-exact replicas of one another. I’ve given this a few months of use now, and I’m fairly certain I’m not missing anything; I understand the settings. It makes no difference, as I’m consistently finding duplicates by going through my files myself, which uses a lot of time. This essentially defeats the purpose of the software; if I have to check its work, all the time, then it’s not truly working at all.

The one thing it does exceptionally well is find *similar* photos—e.g., two photos snapped within moments of each other which are almost alike but which aren’t truly duplicates. I use this program for that. For duplicates, I use Duplicate Detective, which does its job perfectly.

This may just be me. I uses Photos to organize my collection. I have tens of thousands of images. Perhaps others will have better luck in other systems.
