How does files get broken up in packets when transfer over

File Transfer Protocol (FTP) is an application layer (Layer 7 in OSI) protocol used for file transfers. It uses TCP underneath for orderly transfers.

FTP sends files one at a time in the form of data streams, and then it closes connection afterwards.

Bit Torrent is a Peer 2 Peer protocol, files are downloaded in chunks owned by various peers in the network.
