How to prevent files being transferred out of network computers

After Floppy disk, USB ports have been disabled and FTP is blocked by the
firewall, are there any other ways to transfter files out except emailing
them via Outlook and Web Emails (like yahoo, hotmail...)? Is there any way to
prevent files being transferred out via web email (or at least logged)? Is
there any way to monitor or stop large amount of files being tranferred out
from Outlook?

You might be able to block users access to these sites depending on what/how
your network is sharing the Internet access.

If you are running Exchange you might prevent some of this by limiting the
size of files your users can send.
That doesn't mean they can't get a file splitting program and split the
files into sizes below the radar and send them that way.

Sometimes technology can't do it all. You might consider putting in place a
written policy against these types of activities and have your users sign
off on it. Of course management has to back you up and there has to be
consequences for violating the policy.

Not really, no - the current thrust of NTFS permissions etc. doesn't
really protect against copying files out of the system, while still
allowing these files to be used within the system.

Microsoft has started on this approach via DRM, as supported by some
MS Office applications. But it's tricky, given generic capabilities
such as copying and pasting from within one file to another, and the
simple expedient of photographing what is displayed on screen.
