In the dialog box, open the \sample1 folder and then open the Sample1.dep file. The Project Window, docked on the left, now shows the resources for the project in its various tabbed panes.

Hint: The Project Window can be re-sized. Drag its right edge to the width you prefer. It can also be undocked or re-positioned. Drag it to the position you prefer using the region just above the Project Window tabs. You can also undock it by double-clicking that region or the outside edge of the window. While it is undocked, you can re-size it both vertically and horizontally. To re-dock it, double-click its title bar or drag it to the side you prefer. If you accidentally close the window while it is undocked, display it again by selecting Project Window on the View menu.
