How to use it

• use a terminal to run python server.py in server directory
• use another terminal to run python client.py in client directory
• under client terminal, use commands:
  • $ listallfiles
    • List all files in server process' current directory via TCP
  • $ download filename
    • Download one file from the server process' current directory by name via UDP
    • To avoid packet loss and congestion, I add time.sleep(0.002) for each packet sending iteration. It may take a little bit longer time to transfer for a large file.
  • $ download all
    • Download all files from the server process' current directory via TCP
  • $ exit
    • Graceful termination of the client and server applications by properly closing any open sockets
