Try...... Share Ware .com Tucows .com One of the two of them has free download called "COOKIE CUTTER" I used to use it all the time, now I just watch where I go... Another good one is called WINDOW WASHER...That gives you about 90 days,then gotta send them some money.... Either way, It cant hurt to physically go in and clean them out...You'll be shocked by how much wasted space them little buggers take....
