I have both ISD Rome scenery installed and Napulevola's Naples scenery installed. In both sceneries it says to replace the AP951170.BGL with one provided. Now I and not sure which one to use. The Naples scenery has a file named AP951170_LIRF2005_org.BGL in a backup folder. So now I am a little confussed.The Rome scenery can be found at flightsim and the Naples scenery can be found here in the library.

Ok I need to use the AP951170.BGL that came with the Naples scenery. Without it the Naples gound textures are messed up. But Im still unsure what to do (if anything) with the AP951170_LIRF2005_org.BGL file that came with the Naples scenery in the back up folder. There is no mention of that file in the readme.

I believe that this is a copy of the original file which has been replaced. If you need to uninstall the scenery you need to use this file again to put things back to the original state.My original file, is in a file called, scenery /Eurw/scenery/back up iSD LIRF2005. steve

Thanks I understand now.
