1. If your "Belkins" cable is a crossover ethernet ,plug it into each pc's ethernet port and run the "Home networking wizard" using ICS(Internet connection sharing) then transfer your files.
2. If it's a usb file & transferring cable, then plug it into each pc's usb port,select files and settings transfer wizard from system tools and follow the instructions.
3. My favourite one......it's quick & it's FREE!
Take the harddrive from the old pc and put it in the new machine as a slave after changing jumpers if needed,then start transferring files.
