Thanks for pointing me in that direction...it is helpful.

I was able to "back engineer" the formula by seeing how a ACE compliant folder was built and placed in to the variants folder of ACE folder within FSX

Is there a way to assign the flag to the aircraft, for example I assign the USAF flag to a ACE installed repaint, next time I go in to the aircraft for loadout and payload configuration it has another flag as the base option. And while easy enough to re-select the flag, I was curious why it is going back to the USMC flag???
