Using Frigate you can navigate not only through drives a, c, d, e but also through Windows virtual folders such as My computer and others.
To display all of them in Change Drive Dialog (more details) () is not convenient. Besides you use some drives more often than others. So you can set change drive option as you like.
To do it press right mouse button on Drive Tune Dialog and select Drive tune or press the button with a wrench.
You can make additional pages for those folders\drives you use seldom.
