To test, install 3COMDaemon in two PC (one server and one client), in the client, tick all RFC's and use 32000 blocksize.

Since 3COMDaemon uses block size, timeout and transfer-size negotiation, its up to the TFTP client to negotiate the blocksize from 512 to 65464. Because it is a TFTP server, it has little impact on the system. It is one of the best free TFTP servers with minimalistic design and a simple layout.

To download the Cisco TFTP server, you need to be a registered member of the Cisco site with a login ID and password. Since blocksize is 512 bytes, 32 MB is the file size upper limit. Many existing TFTP implementations are incapable of transferring files larger than blocksize*65536. That's why there's a misconception that TFTP cannot transfer bigger file size. Cisco, Solarwinds, etc.) which uses old TFTP implementations. Many people is using freely available TFTP applications for windows (i.e.
