Transfering files from laptop to desktop. Ethernet cable, no router.

I have alot of files I need to transfer from the laptop to the desktop.

All I have is an Ethernet cable, no router. I was trying to set up a a p2p (or PnP) connection between the 2 machines earlier to transfer files between them.

Basically what I did was go to the network connection Properties->TCP/IP changed the IP’s to 10.0.0.1 and 10.0.0.2 as well as the one below the IP to 250.250.250.0 on both.

I was able to open a command prompt and ping the other machine from both sides but was still unable to transfer files.

What am I doing wrong?
