Dup Detector finds duplicate or near-duplicate images by comparing image pixel data. As large image collections can over time pull in duplicates with different file sizes and different names, this program helps track those down and save disk space.

Note: main website down, linking to archive.org

Runs on:WinXP / Vista / Win7 / Win8
Writes settings to: Windows registry. It was a tough call, but I finally decided to accepted it as portable because it is probably not something that you will run that regularly. And when you run the program on a different machine, a few parameters will need to be adjusted anyway.
Stealth: ? No. A yaP configuration file to make Dup Detector portable and stealth is available at http://rolandtoth.hu/yaP/#examples
License: Freeware
How to extract:
  1. Download the installer and extract to a temporary folder
  2. Move the contents of {app} to a folder of your choice
  3. Launch DupDetector.exe

It's such a shame this program is no longer being maintained. It's the best image dupe detector I've ever tried but it could sure use some updating.

This software is old.
I did not manage to make it work under Windows 10.

Since the license says it is freely distributable, I have added a direct download link for those of you who still want it.
