FTPS Connection

I am very new to WinSCP and am interested in running scripts to transfer data between my machine and a Yahoo Web Hosting Server. Yahoo changed their protocol acceptance from FTP to FTPS back in February of this year.

I am running Windows XP Service Pack 3 with WinSCP 5.1.3.

Question

How do I configure WinSCP to transfer data using FTPS?

I see SFTP, SCP, and FTP as protocols. But I don't see FTPS?

Where exactly are you missing FTPS?
Have you seen https://winscp.net/eng/docs/session_url ?

You should also upgrade.
