Is it correct that it's possible to run several web sites under one account placing websites into sub-folders like this? \Root www.domain1.com -> \Root\Site1 www.domain2.com -> \Root\Site2
Yes. So long you make those folders as an application starting point folder. You may want to look at this kb article. http://support.Winhost.com/KB/a635/what-is-the-application-starting-point-tool.aspx Also, you will need to setup a redirect script on your root so those additional domain names you point to your account is redirected to its own subfolder.
