Attached Link: dittoGui download

On Mac OS X, if you just drag a product's extracted Runtime folder into the parent folder of your library Runtime, it says that the folder already exists and do you want to replace it. NOOOO!!! Unlike Windows where it will merge the new into the current Runtime.

I use dittoGui, written by the Bracey clan down under. It's a very neat and simple utility where you drag the source runtime folder onto one little box, and the target runtime folder to the other, and press the 'Ditto' button. It does just what the Windows drag and drop copy does (including replacing any files by the same name that already exist).

You can do it from the OS X command line, but dittoGui is much easier.
