Missing "Use as Defaults" box in "Show View Options" I am trying to change the default size of my icons and their grid spacing as was asked in this question. For whatever reason, my Mac does not have a Use as Defaults box in Show View Options. Do you have any idea why it doesn't or what, if anything, I can do to make it so it does?

I checked the answer given to this similar question, but believe I am already in the correct view, as evidenced below. Any ideas on how I can fix this?
All My Files isn't a folder, it's a special view in Finder. Navigate to a real folder such as your Documents folder and the View Options window will show a Use as Defaults button then.
