I know how to add new textures to a SimObject folder but, if I want to delete a scheme, can I just reverse the process? We've all got various aircraft that we look at and say 'what colour-blind moron picked that scheme to include in the package?'. I also can't see me having any use for a Chilean or Ghanaian scheme on a plane so can I get rid of it by removing/moving the texture folder and thumbnail (if external to the folder) and editing the aircraft.cfg to reflect the change (making backup files first, of course)? Will it work on default FSX aircraft? Some of the stock airliners use what appears to be the same thumbnail which is obviously incorrect. They can be replaced with new screenshots but, since I haven't even loaded one yet, I don't know if I'd even bother. I'd probably use payware replacements in any case.
For example, I have the Flight1 DC-2 and there are at least 40 textures for it. Obviously, there is no way I'm going to need every one of them so I'd like to 'trim the fat' a bit. I have no intention of removing any stock folders or AI aircraft (it'd probably screw something up somewhere else) but I'd like to cut down the visible aircraft options in the selection screen.
