The Finder
The Finder is a special application in Mac OS X, because it oversees the Aqua environment and allows easy access to all other applications. It never stops running while you’re logged in.

You can activate the Finder any time you want by clicking this icon in the Dock — it’s always available (it may be invisible, but it’s easy to find).
Although the Finder is special, it acts like other applications in most ways. It has a menu, submenus, windows, utility windows, and so on that can be manipulated just like those provided in other applications. We begin our in-depth discussion of the Finder with the Finder window.

list view, and column view.
A user can select his favored view by clicking one of the three
mutually exclusive view-control

Finder’s toolbar. We present the same Finder window
