How do I transfer music from my Samsung Gravity 2 phone memory to its micro sd card?

I bought a Samsung Gravity 2 the other day, along with a 4gb micro sd card to go with it. I transferred mp3s from my laptop to my phone using bluetooth, but it saved on the phone memory itself- not the micro sd. How do I move the mp3s within my phone from the memory to the card?





Thanks in advance!|||when u find what u want to transfer, open options, On my phone it says 'move folder' then u find where u want to move it to. Hope it works for you.
