I would like to create a client/server file transfer application but I need some advice. Once I establish a connection using TCP/IP how easy is it to send files?

Do I need to establish some kind of protocol to send it? I've never transfered files through TCP/IP connections before and I'm curious as to how it's done. If anyone could give me advice or point me to some cool FAQs or tutorials on the subject I'd be very grateful.

Also, would it be better (if this is possible) to connect to an FTP server and use the FTP protocol since it's been around a while and is pretty reliable.

Let me know your input, thanks in advance, i love this place!
