Best answer: Assuming you are talking about Ethernet, and probably two Windows PCs, this is something I used to do regularly between an XP laptop that I got in 2003, and a much newer Windows laptop. When I wanted to backup or load a lot of files on the old XP machine from external USB devices, it was really slow connecting the devices on the old laptop as it only had USB 1.1 ports capable of only 12 Mbps in bursts but with much lower average speed.
As both laptops were normally used on WiFi, but both had Ethernet ports, which were never used except occasionally at home. I set the Ethernet ports on both to work on my home network each with their own static address in the home subnet, which were outside my router's DHCP address pool and otherwise unused. I set the network mask, gateway address and DNS server address to match those normally provided by DHCP.
I used a crossover Ethernet cable plugged directly into the two laptops. As they have static addresses, they were immediately able to communicate with each other.
Using Windows/File Explorer on one of the laptops, I mapped the appropriate drive on the other laptop. It may require some changes of permissions to allow full access to the remote system. Plugging the USB drive into a USB 2 port on the newer laptop allowed files to be transferred to or from the external drive and over the Ethernet connection between the laptops from or to the old laptop at speeds that were much higher than using the old laptops USB 1.1 ports.
I had previously tried connecting both laptops by Ethernet to the router. That was reasonably fast, but slower than the using the direct cable. It was also less convenient having to use cables to the router from each laptop.
I also tried my WiFi network between the laptops, but the half duplex, one packet at a time operation of WiFi made is significantly slower.
Using a direct cable means that the two laptops can be linked together anywhere and do not need a router to provide the network.
I hope this helps.
