Dekstop Icon Folder

When my desktop is full with icons and I attempt to add another one, where does it go? Like, is there a second page of desktop icons? If so, how do I access it?

Since your desktop is really just a folder, it can contain more icons than will fit on the screen.
The best way to access the desktop folder and see a listing of all the icons is to go directly to the desktop folder.
In Windows XP, click on "Start" then on "Run". Type "desktop" (without the quotes) and click "OK" This will open up the desktop folder for you.
