Long ago, TFTP was more common for a wider range of internet data transfers, but its lack of security and authentication makes it ideal these days only for specific internal or private-WAN based usages, generally. TFTP operates simply via the UDP/TCP Port Number 69.

Instead, you would rely on TFTP which can save a lot of headaches when performing a handful of smaller tasks that would be slowed drastically by having to cart a drive to several machines. It can be used to easily and quickly backup configurations for network configurations or router settings, it can easily snag and save IOS disk images, it can serve upgrades with swift ease, and you can even boot a system remotely with no hard-drive at all. Looking more at the technical side, TFTP can be quite novel in its uses. However, the security of TFTP is very low. TFTP is ideal to configure for larger scale transfers of files, updates, workstation configurations, and more. TFTP is lighter weight and has a smaller footprint than FTP making it faster and easier to setup than an FTP server on Windows. Click here to learn how to setup and configure Windows 10 TFTP Client.

TFTP, as the name's similarity to FTP suggests, is a file-transfer protocol.
