Decent, not great

I tested this program on my wallpaper collection (2000+ images of varying resolutions).

* Caches images, very fast after first initial scan.
* You can mark matches as mistakes so they're never shown again.
* Image previews are shown proportional, so larger images appear larger and vice versa.
* Easy to use interface.

* Only finds near-exact matches.
* Missed many matches due to crops or differing resolutions which other programs found.
* Turning up the threshold even a couple percent will result in hundreds of false duplicates.
* I found the toolbar buttons for deleting images confusing, and had to be careful of what I clicked.

A good freeware for finding duplicate images and I do recommend it, but I find that Visipics is better at finding similar images.


Many people probably don't know it

I think it's the best overall, and it continues updating.

For getting rid of duplicated images, I use a file scan first, then Visipics, then AntiDupl, sometimes need Awesome Duplicate Photo Finder. This way is the most efficient IMO.
