you can leave it there. it doesnt matter i think.

You dont need to reformat the .iso with USBUtil or USBExtreme.
Put the .iso in the "CD"-folder that is in your USB-root and it works with OPL.
But dont forget to defragment the .iso after you put it in the "CD"-folder...
Thanks LopoTRI and the other people in this thread.
