Are you referring to the file server used for the downloads page? as that is an actual server run by Zimmy. There were several others before that owned by other people, but there hasn't been an ftp server for Winworld. Some people have there own private servers. Try PMing some one like Duff about them. Otherwise there has never been to my knowledge an ftp server for Winwolrd.
Why do you need FTP access? You can download all you want from HTTP. If you are looking to submit files to WinWorld, your best bet would be to post about them somewhere, and try to get them to an admin by other means.
