It's actually really easy to do with mortscript. I created a mortscript similar to nickm's a while back and also setup a file copy.

xCopy "\Storage Card\Boot\Files\*.*", "\", 1, 1

Of course you would need to change the path. Basically, it will do a recursive copy of any files and directories to the root directory. This requires that you have the files you want copied over exactly as they appear in your main memory.
