TFTP vs. FTP
Trivial File Transfer Protocol differs from FTP in these key respects:
Original versions of TFTP transferred files up to 32 MB in size. Some newer TFTP servers remove this restriction or might limit file size to 4 GB.
Unlike FTP, TFTP has no login feature, so it doesn't prompt for a username and password. Avoid using TFTP to share sensitive files — you can't protect these files or audit access to the files.
Listing, renaming, and deleting files over TFTP is usually not allowed.
TFTP uses UDP port 69 to establish network connections while FTP uses TCP ports 20 and 21.
Because TFTP is implemented using UDP, it generally works only on local area networks.
