This is an image of a typical Node Tree from the ADFviewer main window. At the top is the root node of the ADF file, named simply "/", and shown with a folder icon. The next line is the "CGNSLibraryVersion" node, marked with a file icon.

Next is the base node for the CGNS database, named "Basename" and marked with a folder icon. The left is a "-" sign, indicating that the Basename node has been expanded, and clicking the "-" sign will collapse it.

Below the Basename node are two zone nodes, named "zone#1" and "zone#2", both marked with folder icons, and both expanded.

Below the "zone#1" node are the following seven nodes.

Below the "zone#2" node are nodes named ZoneType, marked with a file icon, and "GridCoordinates", marked with a folder icon, and expanded. Below "GridCoordinates", the node "CoordinateX" is visible, marked with a file icon. There are additional nodes below "zone#2", as indicated by the length of the vertical scroll bar, but they're not visible in this example.
