Copyright Goodheart-Willcox Co., Inc. Chapter 4 File Management 141 The list of available drives and folders shown in the navigation pane is a tree. A fi le tree can be expanded to display subfolders and the fi les contained within them, as shown in Figure 4-7. Each folder in the tree is called a branch. The last item in an expanded branch is called a leaf. To expand a branch in the fi le tree, move the mouse over the folder name until a triangle is displayed to the left of the folder icon. Then, click the triangle. If the folder contains subfolders, they will be displayed indented below the parent folder. To collapse a branch in the fi le tree, click the triangle next to an expanded branch. There are several folder views in which the content of a folder can be displayed. Some of these views include changing the size of the icons for fi les and folders, displaying the icons in a list, and displaying detailed information about the fi les and folders.
