>VNC is great but it does not provide any file transfer function. Is there any freeware that provides us with a file transfer function over the Internet. It will be great if I can tell my client over the phone to download and install a simple utility so that I can transfer a file to him.

Instant messenger (free) software will provide for this, and there is a lot to choose from (ICQ, AIM, Yahoo! Messenger, MSN, etc.) with varying degrees of interoperability.
