Based on https://www.pcworld.com/article/2927913/find-duplicate-photos-two-utilities-that-can-help.html, I installed http://freepicturesolutions.com/free-duplicate-photo-finder.html on Windows 10, however, it doesn't appear to be Windows 10 compatible and the application will not open.
So, then I install https://www.duplicatephotosfixer.com/, and after an hour of scanning my system, get the following popup. The website didn't list this 15 photo limitation. Well, I can spend the next year and a half doing it...
Software to find duplicated pictures using visual representation for Windows gives 4 options, but doesn't provide any recommendations.
- https://sourceforge.net/projects/similarimagesearch/ has a user rating of 1.
- http://download.cnet.com/windows/visual-search-pony/3260-2193_4-10091863-1.html has a user rating of 2.
- http://www.joerg-rosenthal.com/en/antitwin/download.html hasn't been updated since 2010, and doesn't list Windows 10.
That leaves http://www.visipics.info/index.php?title=Main_Page. Any good?
What about others?
