To copy the file boot.img from the remote computer Host1, type: tftp -i Host1 get boot. Because the tftp protocol doesn't support user authentication, the user must be logged onto the remote computer, and the files must be writable on the remote computer.

In binary image mode, the file is transferred in one-byte units.

Specifies binary image transfer mode (also called octet mode). A tftp server service is no longer provided by Microsoft for security reasons. Installing the tftp client is not recommended for systems connected to the Internet. The tftp protocol doesn't support any authentication or encryption mechanism, and as such can introduce a security risk when present. tftp is typically used by embedded devices or systems that retrieve firmware, configuration information, or a system image during the boot process from a tftp server.
