you don't even have to open anything to perform your search. The search results update as you add more characters to the field.
And, Windows Desktop Search will recognize advanced search parameters to help you find exactly what you're looking for. Just like with Google or Yahoo, you can use AND to find a file with two terms, NOT to exclude a term, OR to indicate one of two terms... and much more.
Never lose a file again thanks to this phenomenal application that will optimize your Windows file searches.
