Thanks guys, kind of what I figured. I'll probably just delete them. One thing I love about RTMM scenery is its compatibility and I know you guys work your butts off to make that so. And, as far as add on scenery in general, and add on sim objects as well, they don't insinuate themselves all over your machine. Delete the folder and that's it. Sure, there are some texture and sound files hanging around but some other scenery may make use of them, too. Try deleting Norton or iTunes that easily. Man, don't even get me started.
