I to have been looking for application or method that will help me recognize and delete unneeded files that are associated with apps that i have deleted. I have removed a number of fairly large files that have been left behind by apps i no longer have installed. But, some are still a mystery and i dont want to delete anything that is still needed but, memory being the precious commodity it is, i'd like to be able to "cut the fat" for lack of a better term. If anyone out there is educated in this area, your knowledge and input would be greatly appreciated.
