This is a list of the commands available when using the Microsoft Windows command-line FTP client :

Command-line options

As you're starting the program from a DOS prompt:
ftp [-v] [-d] [-i] [-n] [-g] [-s:filename] [-a] [-w:windowsize] [computer]
-v - Suppresses verbose display of remote server responses.
-n - Suppresses auto-login upon initial connection.
-i - Turns off interactive prompting during multiple file transfers.
-d - Enables debugging, displaying all ftp commands passed between the client and server.
-g - Disables filename globbing, which permits the use of wildcard chracters in local file and path names.
-s:filename - Specifies a text file containing ftp commands; the commands will automatically run after ftp starts. No spaces are allowed in this parameter. Use this switch instead of redirection (>).
-a - Use any local interface when binding data connection.
-w:windowsize - Overrides the default transfer buffer size of 4096.
computer - Specifies the computer name or IP address of the remote computer to connect to. The computer, if specified, must be the last parameter on the line.
