PuTTY is a set of utilities, not just the one tool. The same place that 
provides PuTTY provides what someone else mentioned, pscp:

You might also consider sftp (part of the above).

You might also have further ftp configuration files, such as 
/etc/ftpaccess, ftphosts, ftpusers.

Other network files can have an effect on xinetd services, but not 
change non-xinetd services (and I *think* sshd can run either directly 
or as a service to xinetd, although I've only seen it run directly). For 
example, identd can be made to be required, and so far I've never 
figured out how to enable auth from a windows machine without 
downloading a 3rd party application (it can probably do it, I just never 
figured it out).

Then nothing is listening on that port. But that doesn't mean ftp isn't 
running, transfer modes in ftp get a bit confusing. Port 21 probably 
means it is running. Can you ftp from localhost? Likely it is a security 
restriction based on something other than firewall rules, such as 
/etc/hosts.deny or /etc/hosts.allow combinations.
