Hey There Alain!
I believe the easiet way is to buy a micro sd card. You can buy them online from ebay or amazon. If you dont want to wait for it to come in the mail you can visit your local Koodo Kiosk and see what they have in stock for micro sd cards.
Once you get home you put the small micro sd card into the micro sd adapter and pop it in the computer. The computer will read the new file and install anything that is required. After that you should just be able to drop and drag your music files into your removeable disk file.
Hope this helps :D
