Windows office question: how do I change the order that the files display when I use "Open, File"?

Question

I accidentally hit some combination of buttons that made the order of the files backwards. I want to restore the original order.

For example, "File, Open" opens the window that used to have the folders first (in alphabetical order) then files (in alphabetical order). Now the files are first and the folders follow, and both start with the end of the alphabet.

Answer 1

If you click the header above any column it changes the way it sorts alphabetically do some clicking up there and it will change.

Answer 2

Just right click and put arrange by.

Answer 3

right click > arrange icons by > name

good luck =D
