I used Gemini 2 on my library of over 40,000 photos and it was surprisingly quick to go through it. Nothing to blame on the accuracy either. You can review the list of duplicate files and will see that Gemini 2 is on spot. However, if you have photos in both JPG and raw format and selected the “similar files” option in settings, then Gemini 2 will list the raw/JPG couples as similar files. If you have a lot of raw/JPG couples then you might deactivate this setting.

The video below gives a quick overview on Gemini 2, a more detailed review is here. In my opinion it’s a simple and very effective and accurate utility.
