file sharing btrw win 7 pc and xp laptop

i am trying to share files on my win 7 desktop with my xp laptop.
my laptop is already connected to my wireless network for internet access. any suggestions

Have you read any of the tutorials on the 'net about file sharing? Perhaps one like this?

Share Files and Printers between Windows 7 and XP - How-To Geek

before you replied i went on the xp laptop and followed the xp help files and set up a connection but, i have a problem. my win 7 desktop identifies it as a music media server. i have a music media server program on the xp (tversity) and it is identified as "xxxx-xxxx:Tversity Media Server"
also, on a liitle different subject. on the xp laptop i tried to select a shared file from the win 7 desktop to use in a program but, it would not let me do it. any ideas?

Have you reviewed any of the tutorials available on the 'net, like the one I posted?

when i click on that link i get a 404 server error.

Works fine for me. Just google for "windows 7 xp file sharing" and you'll find a ton of links about it.
