G/day  I was looking through the sound folders of the 707 and 727(this is in the CS folder, not the simobjects folder) and noticed that the 727  hasnt got a dill file like the 707 does eg the 707 hase a sound config file , a sound file (with the wavs) a dill file , ace file ect, the 727 has all except the dll, just wondering why this is so, and can anyone explain why there is two sets of sound folders eg one in the simobjects/ airplane folder and one in the msfs/ Cap Sim folder/707,727,757 folder. Also noticed that there is two config files, one for each, but the one in the MSFS/Cap Sim folder is outside the folder with the wavs. When i went to look at what the DLL was titled , it didnt give a description, it just said DLL, so if anybdy could explain it , that would be great, thank you        take care jeff :)
