Between my iPhone, Dropbox, Photostream and also the ones I've manually copied across, I now have an enormous amount of duplicates. I'm trying to sort everything out, and have a new system which will help with all future photos, but for now it's a bit of a mess.
In particular I have around 1,000 photos on Dropbox, and I would like to remove *all* photos that are already in My Pictures, is that possible?
Also, it'd be fantastic to have some software that would search My Pictures for duplicates, show me both locations (ideally with thumbnails so I can confirm!) and then I can remove the duplicates that way too?
I've found some good software for duplicates, but nothing that'll let me compare two directories, nor with thumbnails... is there anything out there?
