PumpKIN is a free, open source application that is used for exchange of data using the Trivial File Transfer Protocol (TFTP). PumpKIN employs a simple, straightforward graphical user interface (GUI) and runs on Windows 95 and later operating systems. PumpKIN makes it possible for a TFTP server and client to transfer large files simultaneously.
TFTP is an Internet software utility for transferring files that is simpler to use than the File Transfer Protocol (FTP) but less capable. TFTP is employed where user authentication and directory visibility are not required. TFTP is used mainly for the purpose of transferring files to and from network hardware and not for general-purpose data exchange.
