The information for each transfer includes the name of the file, the transfer rate, how much time is left to complete the transfer (when the file size is known), whether the transfer mode is binary or ASCII, and the IP address of the client that initiated the transfer.

You can drag and drop files to or out of Transfer, or quick preview, open, rename and delete files in the root TFTP directory in the file management view. The user interface is straightforward, with a file management view for the root TFTP directory and two lists for displaying the status of transfers, one for downloads (read requests) and another one for uploads (write requests).

RFC 2349 – TFTP Timeout Interval and Transfer Size Options.

The app is fully compliant with RFC 1350 – The TFTP Protocol (Revision 2) and provides support for the following TFTP protocol extensions and options: Transfer ‘s primary goal is to address these limitations, offering a user interface that allows you to have complete control of the transfers and the files that can be accessed via TFTP. The macOS’ built-in TFTP server and other available alternatives for macOS don’t support broadcast transfer requests.

No support for broadcast transfer requests: By design, TFTP requests made to the broadcast address 255.255.255.255 should be rejected to prevent unauthorized transfers however, under some circumstances, support for broadcast transfer requests is necessary.

Other TFTP server applications lack this functionality as well. However, because some of the existing applications offer just a front-end GUI to control (start, stop) and configure the root folder of the macOS’ built-in TFTP server, they don’t provide real-time updates of current transfers in progress.

No real-time updates of current transfers in progress: TFTP transfers are very slow therefore, progress updates are essential for a better user experience.

In particular, we identified two main limitations of existing implementations currently available for macOS, including the macOS’ built-in TFTP server :

He shared his frustrations about the lack of a robust and reliable TFTP server solution for macOS. Our friend Sam Clements trusted us with the idea of developing a TFTP server for macOS. For example, TFTP is used to boot diskless workstations or load files to network devices such as routers. The protocol was developed in the 1970s however, it is still commonly used because of its simplicity and minimal memory and processing requirements. TFTP is a high-level protocol to read and write files from or to a remote server. Transfer is a reliable and straightforward TFTP (Trivial File Transfer Protocol) server application for macOS.
