Hi Chris - here's the thing;
Take all the contents from the Avenger folder, cut and paste them into the Files folder. So, the 3do folder will be replaced, but you shouldn't overwrite anything other than stuff that's already in. Safe to do so. Then, just delete the Avenger folder, which should now be empty (if you used cut, not copy - obviously, if you used copy you can just delete the Avenger folder and its contents, anyway)
That should do the trick.
