WS_FTP is the brand name for an FTP client and FTP server from the American company Ipswitch, Inc., currently for the Windows operating system. Formerly available as one of the oldest Shareware FTP clients available, WS_FTP is no longer advertised as shareware. However, Ipswitch, Inc. does provide a 30-day trial of WS_FTP Professional. WS_FTP was originally developed in 1993 by John A. Junod, who sold the marketing rights to Ipswitch in 1996 and worked there as CTO until 2003. The GUI of WS_FTP has been considered something of a "classic"; It has two panes: the left pane is the local computer and the right pane is the remote host. The program has a reputation as a useful program wrapped in plain interface.
