Dear Guest, and welcome to RailUK Forums. Our non-railway discussion forums are currently restricted until members have five or more posts, and you will not be able to make a new thread or reply to an existing one in this section until you have made five or more posts elsewhere on the forum.
Set up a simple home network and copy all the files you want into the shared documents folder on your laptop. Then you can move them to the relevant places. Setting up a network is pretty straight forward. If you have a router you can do it though that, or you can just connect both computers directly with a network cable. Then you need to make sure both computers are on the same workgroup (system properties) and maybe tweak your firewall settings.
Windows also has a built in file transfer program, but I would advice using one of the other methods.
One thing I would add to Craig's post is that if you use the 'direct connection by network cable' method, make sure you use a crossover cable.
Also instead of moving all required files to the 'shared files' folder you could temporarily make the whole C: drive on the old computer a shared drive. Then you could access any files from the new pc and move them across. (Except perhaps for anything in 'My Documents' if you are using NTFS rather that FAT).
