For years now I have lazily managed my photographs into many folders on my PC. I would like to find the dulpicate pictures and delete them. I am compiling all my photographs into Picasa Web Albums, I know the standalone PC version of Picasa can find and delete duplicate photos but I don't want to use Picasa to manage my photographs. I just want to delete duplicated photographs that I have in many folders before I upload them into their respective Picasa Web Album.
Any ideas please on the best program that can find and delete duplicated photographs from pictures stored in Windows folders?
