Paul is looking for a program that can manage his duplicate photos, getting rid of them. Leo says that you want software that can get into the metadata and contents of the image to determine if it's an actual duplicate or not. Easy Duplicate Finder for Windows. For the Mac, Leo uses Gemini 2. AllDupe is a favorite of the Chatroom.
Charlie bought a device from Facebook ads that backs up his pictures, but he ended up with a ton of duplicates. Is there a better option out there?

That way, if it does end up deleting all copies, you'll have a backup on the Mac, there's Gemini 2, which is a de-duper that eliminates multiple copies of the same photo. But there are plenty of Windows versions as well.
