I've copied files like that before to defrag them and it worked fine. When ever I do things with WOW that might mess it up I just back up the UI folder and WTF folder (maybe one more? similar to the WTF folder maybe.). Worse case is you have to reinstall. But it should work. I don't even think you would need to defrag it again.
