FTP Client
An FTP client uses the FTP protocol to connect to an FTP server, to send files in and back up from FTP servers. Basic FTP clients come with many operating systems, including Windows, DOS, Linux and Unix. However, many enhanced clients are available typically as shareware/freeware for Windows and as free software for Unix-like systerms. Many modern web browsers have built-in FTP clients as well (though an FTP client will work better for private FTP servers than a browser).
