Runtime Data

Usage (stderr):

Transfers files to and from a computer running an FTP server service
(sometimes called a daemon). Ftp can be used interactively.

FTP [-v] [-d] [-i] [-n] [-g] [-s:filename] [-a] [-A] [-x:sendbuffer] [-r:recvbuffer] [-b:asyncbuffers] [-w:windowsize] [host]

  -v              Suppresses display of remote server responses.
  -n              Suppresses auto-login upon initial connection.
  -i              Turns off interactive prompting during multiple file
                  transfers.
  -d              Enables debugging.
  -g              Disables filename globbing (see GLOB command).
  -s:filename     Specifies a text file containing FTP commands; the
                  commands will automatically run after FTP starts.
  -a              Use any local interface when binding data connection.
  -A              login as anonymous.
  -x:send sockbuf Overrides the default SO_SNDBUF size of 8192.
  -r:recv sockbuf Overrides the default SO_RCVBUF size of 8192.
  -b:async count  Overrides the default async count of 3
  -w:windowsize   Overrides the default transfer buffer size of 65535.
  host            Specifies the host name or IP address of the remote
                  host to connect to.

Notes:
  - mget and mput commands take y/n/q for yes/no/quit.
  - Use Control-C to abort commands.

ftp

Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012

Transfers files to and from a computer running a File Transfer Protocol (ftp) server service. This command can be used interactively or in batch mode by processing ASCII text files.

Syntax

ftp [-v] [-d] [-i] [-n] [-g] [-s:<filename>] [-a] [-A] [-x:<sendbuffer>] [-r:<recvbuffer>] [-b:<asyncbuffers>][-w:<windowssize>][<host>] [-?]

Parameters

Parameter	Description
-v	Suppresses display of remote server responses.
-d	Enables debugging, displaying all commands passed between the FTP client and FTP server.
-i	Disables interactive prompting during multiple file transfers.
-n	Suppresses auto-login upon initial connection.
-g	Disables file name globbing. Glob permits the use of the asterisk (*) and question mark (?) as wildcard characters in local file and path names.
-s:`<filename>`	Specifies a text file that contains ftp commands. These commands run automatically after ftp starts. This parameter allows no spaces. Use this parameter instead of redirection (`<`). Note: In Windows 8 and Windows Server 2012 or later operating systems, the text file must be written in UTF-8.
-a	Specifies that any local interface can be used when binding the ftp data connection.
-A	Logs onto the ftp server as anonymous.
-x:`<sendbuffer>`	Overrides the default SO_SNDBUF size of 8192.
-r:`<recvbuffer>`	Overrides the default SO_RCVBUF size of 8192.
-b:`<asyncbuffers>`	Overrides the default async buffer count of 3.
-w:`<windowssize>`	Specifies the size of the transfer buffer. The default window size is 4096 bytes.
`<host>`	Specifies the computer name, IP address, or IPv6 address of the ftp server to which to connect. The host name or address, if specified, must be the last parameter on the line.
-?	Displays help at the command prompt.

Remarks

The ftp command-line parameters are case-sensitive.
This command is available only if the Internet Protocol (TCP/IP) protocol is installed as a component in the properties of a network adapter in Network Connections.
The ftp command can be used interactively. After it is started, ftp creates a sub-environment in which you can use ftp commands. You can return to the command prompt by typing the quit command. When the ftp sub-environment is running, it is indicated by the ftp > command prompt. For more information, see the ftp commands.
The ftp command supports the use of IPv6 when the IPv6 protocol is installed.

Examples

To log on to the ftp server named ftp.example.microsoft.com, type:

ftp ftp.example.microsoft.com

To log on to the ftp server named ftp.example.microsoft.com and run the ftp commands contained in a file named resync.txt, type:

ftp -s:resync.txt ftp.example.microsoft.com
