You probably know this already...TFTP is fast but has no directory-browsing abilities or authentication as with FTP. It can do nothing but send and receive files, which is why it is the protocol used for firmware upgrades and configuration backups in most network devices (as baudhayan posted earlier).If I'm not mistaken, it would place the new file image in flash memory and replace the existing file. It wouldn't validate the update... and it does not use FTP.
