In my WinXP, if I go to Start | Run and type "ftp" I get an FTP window, with a complaint of "Unknown Host," but if I charge on and type "Help" I get:

ftp> help
  Commands may be abbreviated.  Commands are:
  
  !        delete      literal    prompt      send
  ?        debug       ls         put         status
  append   dir         mdelete    pwd         trace
  ascii    disconnect  mdir       quit        type
  bell     get         mget       quote       user
  binary   glob        mkdir      recv        verbose
  bye      hash        mls        remotehelp
  cd       help        mput       rename
  close    lcd         open       rmdir
  ftp>

The input "help command gets a very terse description of what the command does, although it does not show what arguments and/or switches – if any – can be used with the command.

Example: If I type "help mdir" I get:

ftp> help mdir
  mdir     List contents of multiple remote directories
  ftp>

(type "bye" to exit the ftp window)

Slightly more detail is found at:

List of FTP commands for the Microsoft command-line FTP client

Site: nsftools.com

"This is a list of the commands available when using the Microsoft Windows command-line FTP client (requires TCP/IP to be installed). All information is from the Windows NT help files."

See also: RAW FTP Commands for additional if needed. The following note appears here:
