Loading music files on Pi mSD card

I know I saw some where that it is possible to use the extra space on the rPi mSD card to store ones music - but I can’t seem to find the documentation on how to do that. Can someone point me in the right direction please?

Hi Mike

There is several threads about “internal” storage
I think this solves your problems
