I recently downloaded SP2 from Microsoft and was amazed to see that the upgrade took an additional 1.2 gig of my harddrive. In looking over some of the new directories which came with SP2, I feel certain that some of them were needed only until the upgrade was fully installed and are now abandoned without being deleted. But then, maybe not. Does anyone know if some of these can be safely deleted? I have tried searching for such info in several places and had no results.
