I have two macs right beside each other on my desk, an imac g5 and an emac g4. I primarily use the imac. I have a cable internet connection, both computers operate on the same cable line through a router. I have a large amount of files I would like to transfer from one computer to the other. About 40 gigabytes worth of files. I'm trying to figure out how to do this. What can I do? My guess would be that ftp is the way to go... but I don't know how to use it for this sort of thing. What's the easiest way I can transfer my files?
