A few seconds may elapse before the transfer begins, then in the File field you

ferred. The cps/bps

cps/bps button allows you to toggle the displayed transfer rate as
either characters per second or bits per second.
If the system does not begin transferring the file, and a time out occurs, you may
see a message indicating the transfer was cancelled by the remote system. In this
case, the system retries the file transfer up to the number of times specified by the
Number of Retries field.

Trivial File Transfer Protocol
Trivial File Transfer Protocol (TFTP) is a simple file transfer protocol. It was designed to
have fewer features than FTP; for example, it only reads and writes files to or from a
remote server. It cannot list directories or authenticate users.
