Resolution
The HELP command can be issued by the client to retrieve information about the FTP server's implementation of the protocol. Most FTP servers will return a listing of supported (or recognized) commands as a response to the HELP command. Because no format for the response is defined, the response to the HELP command is usually only useful to the user and not necessarily the FTP client software. This command can also be followed by a parameter that is another FTP command. In this case, the server may choose to respond with additional information about its specific implementation of the specified command.
