It is simple and operates with low overhead to carry out file transfers faster and more efficiently. Based on this, it is not recommended to use TFTP in moving files or sensitive information on the internet.Īlso, TFTP does not have certain features that you find in more advanced file transfer protocols.

TFTP with UDP provides connectionless communications between Hosts and is most commonly used where File Transfer Protocol (FTP) or Secure File Transfer Protocol (SFTP) is not necessary. Packets are sent with no form of acknowledgment or confirmation.

The communication is such that a Host sends a request for a file to the Server, and the Server responds with the file, but there is no connection established before the sending and receiving of the data.
