I need to count the number of files and folders that exist under a
given root folder on aWindows. Easy to do with recursion and the
java.io.File class. A little slow however. Does anyone know of any open
source solutions ( maybe using native code ) or other cunning
suggestions to quickly obtain the information I need?

Given that Windows itself takes considerable time to generate that
information when you open a directory in MyComputer, I suspect the
directories simply don't have that summary information available.

A strategy might be to scan the directories ahead of time and put up
with slightly out of date information as 4NT does.
