Dreamweaver supports standard FTP, and
you will still be able to connect and transfer files over standard FTP,
even after we upgrade your FTP service to support FTP over SSL (FTPS).
however, does not support FTPS. In order to transfer files over a
secure, encrypted connection, you can build your site locally with
Dreamweaver, but would need to use an FTP client that supports FTPS to
transfer the files to your site.
