how to move and merge folders in OSX Mavericks?

[mrjayviper]

I have 2 subfolders (which in itself contains many subfolders) in my main folder.

e.g.

    main folder
    == subfolder1
    ==== folder1
    ==== folder2
    == subfolder2
    ==== folder1
    ==== folder3
    ==== folder4

some things in subfolder2 are already in subfolder1. If I drag and drop subfolder2 into subfolder1, it will ask me to replace existing subfolders thus losing things. The only way to merge the folders that I know of is to press the option key. But this only makes a copy. This still requires me to delete the unneeded folder.

I want to move subfolder2 into subfolder1 and merge their contents. How can I do it? Thanks much

Learn to use the command line. This is easily accomplished there.

ditto -V subfolder2 subfolder1

will do it (if you are in Main Folder).

Then to delete subfolder2:

rm -R subfolder2
