New Mac users should find it a blessing, and experienced users should find it significantly increases their productivity. In both of these cases, the other files on your computer are also immediately available to you through an alphabetized, hierarchical display. Navigator doesn't require remembering even a single key combination. This makes them immediately available to you without requiring you to perform any additional steps.
Navigator organizes files by volume for ease of access.
Navigator's hierarchical display can be up to five levels deep. Selecting a folder in Navigator automatically opens the folder and displays its contents. Selecting a file in Navigator automatically opens the file in the program that created it. Selecting an application in Navigator automatically launches the application. Navigator is always instantly available because it doesn't require launching an application.
