If you're using a x-over cable, it works just like a hub is in place (assuming you're only using 2 PCs). Add TCP/IP to both laptop and PC. Set IP addresses as below:
Workstation. .IP Address: 192.168.2.10. .Subnet Mask:255.255.255.0
Laptop. .IP Address: 192.168.2.11. .Subnet Mask: 255.255.255.0
These IP addresses will ensure that you will not conflict with any internet addresses if you dial out while the network is in place.
Remember to 'Share' the directory you want to pull the files from (Right-click the directory from within Windows Explorer and select Share, then give full access from the following window). Then log into the destination pc and navigate through the network to the source pc, then the directory. You shouldn't have any problems. If you get stuck, please feel free to e-mail me and I'll give you a complete talk-through.
