New Folder in The Same Folder Window Frame

You open a folder window. Then you click a folder icon inside it. Then you click another folder icon. You keep doing this until your desktop is covered with folder icons. To get around this situation, hold down the Ctrl key. Double click the folder you want to open. When you do this, Windows displays the contents of the new folder in the same folder window frame. It doesn't matter how many folders within folders you open, just one window appears on-screen.
