The TFTP file transfer process completes when the following steps are successfully performed:
1. The client sends a request for a file to the server.
2. The server responds with the requested file or an error message.
3. If the file transfer was successful, the client verifies the integrity of the file by comparing its checksum with that of the original file.
4. If the checksum values match, the client acknowledges the successful transfer.
5. If the transfer was unsuccessful, the client attempts to retransmit the file or reports an error to the user.
Once the file transfer is complete and the client has verified its integrity, the file is ready for use.
