Shoutbox

If you have xp it's easy, just right-click the folder you want to share and press Share and Security and there you can choose a share name. Then if both the computers are one the same Workgroup or Domain, you can see the folders at Start>My Network Locations. Or use the UNC path> press start> Run and type "\\REMOTECOMPUTERNAME\SHAREDFOLDERNAME"

The names of the buttons may vary as i don't have an english xp
