Where is htdocs in OpenShift cartridge?-Collection of common programming errors

I’ve setup an OpenShift account, and used a CodeIgniter quickstart. From the OpenShift Management console, I click through to my URL, and the default welcome_message of CodeIgniter shows up, as expected.

Now I use WinSCP to connect up to my remote site, and find a folder structure that is nothing I recognise. I’ve tried searching for htdocs, and also “welcome_message.php” but am not having any luck.

Can anyone point me to where I might find the htdocs folder etc on OpenShift?

Thanks in advance.
