    (1) I have two folders "folder 1" and "folder 2" 90% of the content on each folder is the same....both large folders over 100GB. On windows you can copy all contents and paste into the other folder and click rename the file and if there is the same file name it would just rename the file name to file (2), etc. On Mac it will give you give you the options of "keep both" and rename is as "copy", but you can only do this if select 4 or less files, if you select more than 4 files it won't give you the option to keep both.

    (2) After I figure out how to merge both can i delete duplicate files? I'd like to sort it by size and file name so i can confirm they are duplicates. Or if there is a way to delete duplicates in 2 seperate folders than i wouldn't need to merge the folders above.

    Take a look at this:

    Compare Folders
    By Pol-Online

    Folder comparison for the rest of us: simple, fast and accurate.
    Compare at a glance two folders, even with thousands of files, taking into account file and subfolders content, creation & modification dates, permissions and more. Easily filter the results to only show what matters to you.

    I have not used it but would make a copy of what you have and run this tool and see what happens.

    If you press Option while in the dialog, Skip will become Keep Both.

    Search for the files with a name that contains "Copy".

    For the second part you can try DuplicateFilesDeleter. The software includes a free trial, so you can try it whenever you want. Good luck ;).
