File transfer is the transmission of a computer file through a communication channel from one computer system to another. Typically, file transfer is mediated by a communications protocol. In the history of computing, a large number of file transfer protocols have been designed for different contexts.
Protocols
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 protocol[1]
- Secure copy (scp) is based on the Secure Shell (SSH) protocol
- HTTP can support file transfer
- Bittorent, Gnutella and other distributed file transfers systems use peer-to-peer
- In IBM Systems Network Architecture, LU 6.2 Connect:Direct and XCOM Data Transport are traditional
- 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
