Seagull FTP was formerly known as BlueZoneFTP.
The program features an attractive Windows user interface and is specifically optimized for midrange and mainframe environments. Note that file transfers are not encrypted.
However, there are better alternatives to this program, as development has stopped, and the company has moved on to browser-based file transfer. Therefore, we suggest here on DLC.dk that you check FTP sektionen, as there are many strong options for effective FTP clients.
