    Very informative and well presented. Just what I was looking for. Many thanks!

    But what if the files are the same name? The first two options don't work. And unfortunately I don't have enough hard drive space for the 3rd.

    Also what if the files have subfolders? And what if some of those subfolders have the same name, but different contents?

    Can't an app ask the system to look at two file structures, and merge the individual files in folders that share a name?

      Not sure how detailed you can get, but in your situation you should also consider the manual route -- just do it by hand and make the decisions yourself. It might take longer, but it might be the only way to get the job done right.

    In my case, I have three folders (backups of music libraries). There are no duplicates within each folder, however when the folders merge there will be some. I am trying the terminal command, merging two of the three folders. It's taking forever, but seems to be working.
