In either the Tree view or the List view, you can set the root location of the view.
To set the root of the current view:
In either view, select View>Set Root from the menu bar or select Set Root from the pop-up menu to display the Set Root dialog box.
If you want the root to be a directory or library, type the path or browse to the path.
In the System Tree, the default root is the current workspace. If you prefer to work in the Library painter, you may find it convenient to set the root to the current workspace. Using the current workspace as your root is particularly helpful if you are using many libraries in various locations, because they are all displayed in the same tree.
