A file transfer protocol is a convention that describes how to transfer files between two computing endpoints. As well as the stream of bits from a file stored as a single unit in a file system, some may also send relevant metadata such as the filename, file size and timestamp – and even file-system permissions and file attributes.

Some examples:

• FTP is an older cross-platform file transfer protocolcite-ref-1[1]

• SSH File Transfer Protocol a file transfer protocol secured by the Secure Shell (SSH) protocol

• Secure copy (scp) is based on the Secure Shell (SSH) protocol

• HTTP can support file transfer

• BitTorrent, Gnutella and other distributed file transfers systems use peer-to-peer

• In Systems Network Architecture, LU 6.2 Connect:Direct and XCOM Data Transport are traditionally used to transfer files

• Many instant messaging or LAN messenger systems support the ability to transfer files

• Computers may transfer files to peripheral devices such as USB flash drives

• Dial-up modems null modem links used XMODEM, YMODEM, ZMODEM and similar
