Well, you'd need to establish an FTP server on your computer, and he would need an FTP clinet, and the appropriate addresses and logins.
Never used CuteFTP, but I'd suggest if you are using windoze get a copy of
Serv-U for your PC (free version), and set it up as an FTP server (only temporarily). Then read the instructions about setting up an FTP server, and how your friend can connect.
Hope this helps
Cheers
Mick
