Learjet 45 ?

Is it posible to repaint the default Learjet 45 model
When i try to open the files Lear_45_2_c , Lear45_c , Lear45_d and Lear45_t it says drawing failed When i attempt to open with paint i just get a white sheet . The only file i can access that even looks like they are textures is file Lear45_t1 , so i started to repaint the textures in this file but when i insert it it does show the extra variation but not the new texture
Is there a special program to access those other 4 files or am i painting the right file
Whenever I looked in the texture folder of the other variation I saw that only the 4 files that I couldn't access where there and the one that I could open (the lear45_t1) was not there . Help wanted please ::). Happy flying
