Okay, so I suddenly thought, put the word windows into the search window on [URL]http://www.sourceforge.net[/URL] and whoa! Many more results than I expected. All sorts of programmes for MS Windows. This after discovering that FireZilla was for MS Windows only at this date. It seems to me that sourceforge is gathering an army to attack MS on another from from the Penguin (Linux). Still the concept of Open source allows many different angles and ways forward.
