SSH File Transfer Protocol
Secure File Transfer Protocol
sFTP

    (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).
