i haven't used zencart in a long time. did it get more confusing, or did i get more stupid?

i want to setup an mp3 store with downloadable products.

each product should have an alternative file that is loaded in a flash player.

setting up the flash player should be easy for me, but i'm totally confused on how to setup products to have one downloadable file and one for previewing. i dont want the store maintainer to have to use FTP, i just assumed everything was possible with file fields.

any advice?

thanks in advance.
