How can I find and delete duplicate photos?

摘要

Q The library on my Windows Vista PC is full of duplicate photos and videos, so I'm looking for a free program that spots duplicates and makes it easy to remove them. Can you help? A Duplicate files are all too easy to create by uploading the same photos and videos repeatedly from your tablet, digital camera or phone, or by simply trying to reorganise your folders. Be careful when choosing a duplicate-finding tool, because some just check for duplicate file names and delete "duplicates" automatically, which can result in non-duplicate files being destroyed.
