About site folders

A site's two folders are its root folder and data folder. If you name your site Mysite, the root and data folders are named Mysite and Mysite.data respectively. After the site has been developed, Mysite will contain the pages and media that are uploaded when the site is published. Mysite.data will contain auxiliary material needed to build and maintain the site. It will not be uploaded.

When you create a new site, you get the opportunity to create a third "umbrella" folder to contain the root and data folders and the site document.

The umbrella folder is recommended.

If you name your site Mysite and create an umbrella folder, you should name the umbrella folder something else, for example, Mysite Folder, to distinguish it from the root folder named Mysite it will contain.
