Mine has become a hodgepodge of this and that, and I have traced some layering problems to this particular folder. I have unchecked it from my scenery library list. But, I am also wondering, are there default sceneries from the fs9 installation that I might be missing. I checked all for cd's but got no helpful infomation. Thanks...Sherm

Some third party meshes and airport sceneries place their folders in there. I do not recommend this since by default it is included in the scenery list as you noted.I have two folders on my FS drive root directory called Common Scenery and AFCAD2s. Under each there is a hold folder.The AFCAD2s is near the top (lowest number) in my scenery libeary ans the scenery subfolder under ADCAD2s gets the AF2_xxx.bgl files, I move them into the hold folder if I do not want them to be active such as in multiple versions of an airport. When FS9 starts it detects and reindexes automaticly for any AFCAD2 files I have changed.I have both FS2K2 and FS9. I have under the Common Scenery Folder a subfolder with each scenery title such as KMSPAirport or Canary Island Mesh. Each titled scenery folder has a scenery and texture folder as needed. In either FS I use the scenery add button, browse to the Common Scenery the scenery title folder, highlight the title, and finish the add process. I then adjust the priority (lower number, higher priority - a mesh should have lower priority than what sits on it and always higher priority than the defaults, although the higher resolution mesh will be chosen).To me this offers a more common effeciently organized manner rather than having items ganged under the scenery and texture subfolders of Add-On Scenery. It also keeps me out of trouble by erroneously eliminating any defaults. If any third party software installs in there, I usually drag it to my organization. It also simplifies backing up customized stuff by zipping up those two folders of Common Scenery and AFCAD2s and burning them to CD (retaining folder paths).

thanks, ronzie...that goes a long way toward solving my problem. But, what about my original question. Does FS9 instally anything in addon scenery by default? thanksSherm

thanks...now I can begin reorganzing and figure out why some runways swallow up my aircraft...:-)Sherm

I use the addon scenery folder as my top level scenery folder, but that's because in FS2002 when I went to add scenery it would default to the addon scenery folder, so it was easy to navigate to the new folder. FS9 doesn't do that, but out of habit I still place my scenery folders in there. I have nothing in addon sceneryscenery nor addon scenerytexture, though the folder is active in my scenery.cfg by default I guess.What I am uncertain about, is if edited default scenery files should be put in their default folders, or into new folders. AFCAD1 put edited defaults back in the same folder but I don't know if that should be considered the best answer or not.scott s..

My take is that you should put them into new folders allowing the default to be just that; default.However, this brings up another question. After loading in a scenery in Addon Scenery, can the new folder be moved out or does it have to stay there?

If you have placed a folder with its subfolders in Add-On Scenery and then move it out after FS has indexed it, it will not be found -- the index includes the location. You will have to readd it as new scenery in its own folder. FS will indicate that it can't find area xxx in the scenery index file. Just readd it in its new location, delete any old entry if still there, and restart FS for a new index.
