Hi Toni251,
any airplane standard root folder structure in CFS2 is as follows:
<model> - the brackets stand for folder -
it includes two files, one that ends with .mdl and a model.cfg. The model.cfg is a simple text file which indicates to the simulator which model must be loaded for a given aircraft, the *.mdl is the actual model and cannot be open with a text editor.
<panel>
it's the 2-d panel folder. It usually contains a minimum of two files, a bitmap image of a given aircraft instrument panel and a panel.cfg. Panel.cfg is a text file which contains all the info about size, number and position of a given aircraft gauges. Speedometer, artificial horizon, vertical speed indicator, magnetic compass, oil temperature and pressure and so on. Sometimes there are more bitmap files complementing the intrument panel.
<sound>
It contains all the sound files for a given aircraft engine. They are all in *.wav format plus a sound.cfg text file which controls how the sound is operated by the simulator.
<texture>
It contains all the Extended Bitmap files of the aircraft livery or "skin". Extended Bitmap files normally need a particular utility to be viewed or modified.
In addition to the above subfolders, in order to have a working aircraft, you will also see in the aircraft root folder the following files:
aircraft.cfg: a plain text file which contains the name of the aircraft as it will be displayed in the Free Flight menu, aircraft empty and loaded weights, flight envelope information, contact points (how the aircraft sits on the ground and the so called scrape-points, which you do not want to know where they are because it means you just crashed), flaps positions and degrees, cockpit lights and, if the aircraft is a naval model, arresting hook and folding wings info.
(aircraft_name).air: all the necessary information CFS2 needs to make a given aircraft fly. This also needs a particular utility to be opened and, eventually, modified.
(aircraft_name).dp: Damage Profile file. A plain text file which contains all the info about battle damage occurring to your aircraft, effects triggered by battle damage, extra effects like exhaust flames, type and quantity of payloads your aircraft can carry as they will be displayed in Free Flight, wing hardpoints where your payloads will hang, gun displacement and harmonization parameters, ammunition total quantity and general info used by CFS2 to assign to the aircraft an allegiance in combat, ceiling and minimum altitude, top and minimum speed, date of deployment and crew member(s).
Any of the above missing, misplaced or corrupt and your aircraft will not be displayed in Free Flight.
Any aircraft folder must reside in CFS2 root \AIRCRAFT folder to be operative.
Phew! Did I miss something? I hope not. I also hope this will help your adventure in the wonderful world of CFS2. Some of us have been at it since it was released back in 2000 and still having fun and new things to discover to date.
:welcome: to SOH!
Cheers!
