For orientation and navigation purposes the navigation path ("Breadcrumbs") is displayed.
As you go deeper into the directory structure, the selected directory is added to the breadcrumbs row (navigation path), so that you can see the current selection anytime.
You can jump directly into a level by clicking on the directory symbol.
Via arrows you can display the respective subdirectories. When moving the mouse over a directory, it is colored. With a click on it you can load the respective level.
