We offer FTP + TLS encryption for uploading files to your hosting account securley, many FTP clients will use this by default now.
FTPS is simply using the FTP protocol with TLS encryption enabled. Nothing changes from the server perspective. The port, host name, username and password all remain the same. Most modern FTP clients will have an option to enable encryption. There will be an option to enable TLS as the type (not SSL).
Note: Your FTP client (e.g. FileZilla) will likely give a certificate error as the FTP host name will not match the server name *.quick.net.au. You will need to accept / ignore the warning, but the connection will still be secure. You can avoid the certificate error by using the server hostname which will be hostXX.quick.net.au form your hosting setup instrucitons where XX is the number of the server hosting your site.
If your connection fails while trying to get the directory listing then check you have selected Passive Transfer mode and NOT Active and that your FTP program can make outbound connections to ports 49,000 - 49,999 which the server will use for the actual data transfer.
