I guess I didn't explain myself enough my friend. I always do exactly as you say. However. The sound file I,m trying to transfer won't work with the aircraft file that I,m trying to transfer the sound to. Please know that your help is greatly appreciated. I'll keep studying my situation and hopefully come up with an answer soon. Thanks again.

I'm pretty sure I understand what you want to do. All flyable aircraft will have a sound folder which is usually named Sound. This contains a file named Sound.cfg.
Unless the Sound.cfg is aliased to use the sound from another aircraft the Sound folder will also contain a number of WAV files. These should be regarded as a sound set & kept together. The FSX default aircraft also have a folder named sound.ai which I assume is used when the aircraft is used as AI traffic. This shouldn't affect the sound of the flyable version of the aircraft.
Transferring the sound from one aircraft to another is usually a simple matter of copying the complete Sound folder & pasting it into any aircraft you wish to use it, replacing the original Sound folder. In some cases this might not be named Sound so you must make sure that the new folder name is exactly the same as the original folder used in that specific aircraft. For example; some aircraft might have sound folders named Sound.GE or Sound.RR depending on the engine used on different variations. The folder used by each variation will be defined in Aircraft.cfg.
This should work just the same in FSX as with all other versions of FS/CFS. Which sound files did you wish to use in which aircraft? I should explain that I only have the FSX Demo so if this involves default aircraft I might not be able to check it out for you.
