|FTP is an acronym for File Transfer Protocol. As the name suggests, FTP is used to transfer files between computers on a network|
|FTPS (commonly referred to as FTP/SSL) is a name used to encompass a number of ways in which FTP software can perform secure file transfers. Each way involves the use of a SSL/TLS layer below the standard FTP protocol to encrypt the control and/or data channels|
|SSH is a secure network protocol that lacks the simplified file transfer commands of FTP.|
|SSH File Transfer Protocol or SFTP is a network protocol that provides file transfer and manipulation functionality over any reliable data stream|
|1. FTPS was created as an extension of FTP to add security mechanisms, while SFTP is an extension of SSH that adds easy file transfer capabilities to the already secure SSH.
2. FTPS uses two channels to facilitate communications and data transfer, while SFTP only uses one.
3. FTPS sends and receives messages in a human readable format, while SFTP sends and receives messages in binary.
4. FTPS has the advantage of being widely known, while SFTP has the advantage of being more secure.
