File Transfer Protocol (English: File Transfer Protocol, abbreviated: FTP) is an application layer protocol for file transfer between a client and a server on a computer network. Generally, FTP software is often used when using virtual hosts, or some other special-purpose file transfers require the use of FTP clients.
