FTP utility is a TCP/IP utility for copying files to and from remote hosts on machines running Microsoft Windows family operating systems. The remote host must be running the FTP service and authenticate the client before the client can transfer files.
The FTP utility provides a command-line interface only for uploading and downloading files to FTP servers. Various shareware GUI-based FTP clients are available on the Internet.
How it works
The FTP command starts an interactive session in which a series of FTP-specific commands can be used to list directories, upload and download files, change between binary and ASCII mode, and so on.
The FTP command is a command-line FTP client and must interact with the FTP service running on the remote host. Microsoft’s implementation of the FTP service is part of Internet Information Services (IIS).
How to use ftp utility
Opening an FTP site
To open an FTP site, perform the following steps:
- At the command prompt, type the following: ftp ServerName
- The prompt changes to ftp>
- Type anonymous when prompted for the user.
- Type any password.
- Usually, when servers allow anonymous users, any text can be supplied for the password, including no text (just press the ENTER key when prompted for the password).
