This seems to be the best forum for this... I have two computers, both running Windows XP. I need to move about ~20gb of files from A to B. Computer A has internet access, but B has none. Also, I do not own an external hard drive. I do have a cat 5 cable that I can connect the two with, so I thought I could transfer the files directly using that somehow. Is this possible, and how would I do it?
Yes you can do it. I believe you will need a cross over cat5 cable to connect 2 computers together without a hub or switch. You will have to give them an ip each, same submask and some workgroup. You will now be able to browse shared folder of each one. For more info browse google for "Peer to Peer network"
Well, these days cross-over cables aren't needed too...and a patch cable works. The NIC automatically detects and reverses connections virtually if required.
you could make a cross over and do peer 2 peer if you can physically have both machines near each other.
