On english versions, this is the 'Start in' field. When you create a shortcut to the executable instead, Windows allows you to explicitly the working directory. If you just double-click the executable, the server will serve everything in and below the path where the executable is located. Without these restrictions, all files on the host system would be accessible via TFTP. The server will refuse requests for all files requests with '.', slashes and colons due to security reasons. The server always listens on UDP port 69 and provides remote access to the working directory where the server has been started.

If you think that you need 64bit binaries, TFTP is quite definitely not what you need. If the signatures are missing or broken, someone managed to break GitHub or take over this repository. At least verify the 'Digital Signature' if you just download the binaries instead of building the code yourself. These binaries should be code-signed with an Authenticode certificate. The Binaries directory contains pre-built binaries of the tftp client and server executables.

Several Windows variants either ship with no TFTP client/server at all or they do not support the RFC2348/RFC2349 options.

Unfortunately the basic TFTP protocol RFC1350 is not very good at transfer speeds, even on 100% error-free links where none of the UDP packets are lost.Įspecially the RFC2348 Blocksize option can massively improve throughput. TFTP is also one of the transfer options supported by u-boot. It is still widely used in embedded software R&D environments to bootstrap or update devices because of this simplicity. The binaries and code found in this repository work, but this project is old and not actively maintained (feature-complete, nothing else to do except cosmetics). Free TFTP client and server for Windows, with RFC2348 (Blocksize option) and RFC2349 (Timeout interval, Transfer size option).
