I am on the single site plan free trial. I have created a sub domain. I tend to put my api project here then my web application in the main virtual application folder which already is created for me. However I don' t see any option to add folder on sub domain. There's only delete option. How can I accomplish this.
For each site account, you are only afforded one virtual root folder which I believe you are asking for. If you want to have another root virtual folder, you may want to consider upsizing to a multi-site plan if you don't have one already. This will allow you to setup another Site account with it's own virtual root folder and assign your subdomian to it. http://www.everleap.com/cloud-hosting/multi-site/overview/
