FTP file transfer happens via 2 channel. command channel and data channel. where command channel responsible for user,pass ,quit and it will be active still sessions active. Other process like data transfer and receive will happen via data channel. No encryption and it can be decoded and readable via global network.
In SFTP, it uses secure shell for this process and both command and data transfer happens on same encrypted cipher method. Due to this it is secure.
