Thread: MS slows down

Hi , I am a newbee on this fantastic forum.
I use my Garmin 60csx a lot for backpacking and on the bicycIe. I have a lot maps loaded on my windows computer (xp ) and I was wondering if Mapsource can get slow if too many maps are in the Garmin folder ( all my maps are in the Garmin folder on :C) When I started with the Garmin GPS last year I installed a lot of crap maps in Mapsource (Now I use a patched 16.6.3 version ) and some of theme can,t be uninstalled by windows (no uninstaller ). Is their a way to get rid of maps in mapsource which have no installer ? and is their a limit on the number of maps mapsource can handle without slowing down ?
thanks !
Jeremy.
