you cannot download memory! a computers/mp3 players memory is not a peice of software you can download of the internet. The capability to be able to store information is done so by having the appropiate hardware. as the previous posts suggests you may beable to buy additional space from the makers web site but as far as i am aware you cant do this for mp3 players. you will just have to buy a better mp3 player.

I know the lasest ipod has a 60gig HDD which will be pretty hard to fill up with music alone...
