Do you mean FTP? Why? There are plenty of freeware FTP clients.
Yeah, but many of those freeware tools don't have nearly as much functionality as WinSCP. I've run into a similar scenario where one of our clients stores his data on his own SFTP site from which we download some data, but then we have OUR own site, which is a standard FTP site on a Windows server, onto which our other clients UPLOAD their data. With the alternative security offered on the Windows server, our system administrators don't use the SSH protocol at all. Thus, I can't use WinSCP. Kills consistency between my shell scripts.
