SFTP is an acronym for Secure File Transfer Protocol. Like FTP, you can use SFTP to transfer files. Unlike FTP, which transfers all files and log-in information in the clear, SFTP encrypts all of the information being exchanged.
Even though the name is similar to FTP, it’s an entirely different and unrelated protocol that uses SSH (Secure SHell) for all communications. As a result, you can’t use SFTP anywhere you can use FTP. It must be explicitly supported on the server to which you’re connecting.« Back to Glossary Index
