Project Explorer
The Project Explorer organizes all of the screens, worksheets, and other items that comprise your project and presents them in an expandable tree-view.
To open a folder and view its contents, either click the Expand icon 
to the left of the folder or double-click the folder itself.
To close a folder, click the Collapse icon 
to the left of the folder.
If you right-click any item in the Project Explorer, then a shortcut menu will appear with contextual commands for that item.
There are four main sections, or tabs, in the Project Explorer: Global, Graphics, Tasks, and Comm.
