[arch-general] Sharing data between Windows 7 and Archlinux

Hi all, Got hold of a cheap laptop. I want to use it as my download rig. It will be on most of the time downloading torrents. The laptop actually came with Windows XP installed. I setup the laptop ip as 192.168.1.5 and my desktop (running Windows 7) ip as 192.168.1.4. After doing that I connected both of them using a lan wire. I then enable sharing on both of them and I could transfer files directly from one computer to the other at speeds of upto 75MBps. I want to know how to do the same with archlinux or Windows 7 running on my desktop and archlinux running on the desktop. Please tell me how to do that. I want to be able to tranfer downloaded content directly from the laptop to the desktop using a lan cable. Thanks.
