SFTP is an acronym for the SSH File Transfer Protocol. SFTP is the preferred option to FTP because it is inherently more secure and is able to piggyback on an SSH connection.
You may have often found yourself on a linux console where you need access to a file that you have stored on Google Drive, an Amazon S3 or Azure instance, or perhaps you want to transfer a file back from a local file system to one of these accounts. In either case it would be good to be able to do this without installing and setting up additional software.
