A folder is a group of saved views, often related by theme (for example, a folder named Content Type might contain the views Course, Layout, and Lesson). They are used to organize your content in the sidebar of the web app, so that you can maintain an organized navigation for your space.
To add a folder, click the "Add folder" link at the bottom of the sidebar. The Add folder dialog will open.
