i can't find it any where
Go into the main (Flight-Simulator9) folder, there are two folders: 1scenery and 1add-on-scenery.
Hey there rich_bro,
Unless you are referring to the place where you at to simulator. Fire up FS9. on your 'Select a Flight' page, click on 'settings' at the bottom left hand column, then 'Scenery Library'. This brings up the area where you actually add the scenery to FS. Locate the specific folder as stated in the previous post and then click 'Add Area'. Then shut down FS and restart. Your scenery is now visible in FS.
