Transferring files over ethernet or USB or wireless

[shadow29]

I've got a desktop and need to transfer several gigs worth of files to a laptop. Not practical to do it by CD.

I have a wireless network set up (the desktop is connected to the router via ethernet and the laptop connects wirelessly). Can I transfer files that way?

Or via ethernet or USB? I have both cables.

Also, please explain it simply.

Thanks,

John
