The Finder Windows
The Finder windows display all the contents of your hard disk and other removable disks you might put in your computer. Learning how to "navigate" your way around the windows is one of the most important skills you can learn. There are three "views," or different ways you can see the contents of a window, as shown in the examples below. Choose the view you feel the most comfortable with. See Chapter 6 to learn all about finding your way around and controlling and customizing your windows.
Notice the file "robin" is highlighted, or selected, above. This indicates that the items in the column to its right are contained within "robin."
Notice the folder "Documents" is highlighted in the second column, above. That indicates that the items in the column to its right are contained within "Documents."
The items in the third column are contained in the folder called "Documents."
Click the red button (x) to put the window away. Click the yellow button (-) to send the window down to the Dock, called minimizing; click once on its icon in the Dock to make it visible again.
Click the green button (+) to enlarge or reduce the size of the window (each click will do either one or the other, depending on the current size of the window).
