With windows (or virtually any other O.S. (Mac OS X, Linux, Unix, ...), there is a free CLI ftp program. For example, on windows, fire up, "Start" > "Run" > "cmd.exe". Then you get a shiny dos(-like) prompt. Type "ftp" (followed by <enter>) and you are ftping.
Code:
open ftp.server.com
Other useful commands are
put, ls, mkdir, rm, close, quit and so on. Also try
help.
