In my case, the biggest issue was with music files, where I had renamed and, in some cases, moved the files, but they were otherwise identical. I was comparing directories/files on a drive from one computer to ones on another, which were newer. And please forgive me, if it is already existing and I just haven't found the option for it. after all, WinMerge will tell me that IMG_1234.jpg in Folder0307_110812_Test.jpg in Folder2 are identical.if there are files with identical size, have a closer look with a binary comparison.check if there are files with identical file size (only then they possibly could be identical).So, what I have in mind if I want to find identical files: The way I'm currently using WinMerge, WinMerge will tell me that the files are 'left only' and 'right only'. In the first folder they have to original name from the digital camera, e.g. I compare 2 folders with identical files but they are renamed in the second folder. One question, about a compare mode which I haven't found yet. I'm using it to clean up old directories etc. It's really a very useful piece of software.
