Just as you often need to rearrange the items on your desk or work surfaceperhaps to put the papers you're working with on top of items you don't need at the momentyou'll often find it useful to move windows on the Finder desktop. You can move a window so that only part of it is visible on the desktop, but you can never move it entirely off the desktop.
Follow these steps to practice moving windows:
1. Position the pointer anywhere on the title bar of the System.Disk window (except on the small square at either end).
2. Drag the title bar to move the window to a new location.
As you drag, a gray outline moves with the pointer to indicate the new location of the window. When the outline is where you want the window to be, release the mouse button. The window moves to its new position.
