Thank you for correcting, but there is a solution for that;
There is no such Sftp, they name it Sftp because it is a secured protocol connection.
Indy10 FTP has added Security Options that make's ftp SFTP, if you will use indyFtp and not using the security options, that makes your protocol connection FTP only.
By using the security options, that make's Secure as the name Sftp.
To all experts and to you, Correct me if I'm wrong again.
