SSH File Transfer Protocol

(SFTP) A version of File Transfer Protocol (FTP) using an encrypted network connection provided by Secure Shell (SSH), usually SSH 2.

The SFTP protocol allows for a range of operations on remote files, making it more like a remote file system protocol. SFTP clients can resume interrupted transfers, get directory listings and remove remote files. SFTP has largely replaced Secure Copy (SCP).
