I may be about to reveal the depths of my ignorance, however, in the interests of possibly adding to the amusement of fellow members, here goes.
Recently I was in my OS drive for my machine, which is E: drive. While there, I visited Documents and Settings/Owner/Application Data/Microsoft/FS9 and discovered I have a complete duplicate of my "Aircraft" folder for my FS9 installation. With a few minor differences, there is one for my FSX installation, too. This could add up to a lot of space on the machine used in a duplicative manner. What is the reason for this duplication of "Aircraft" and "SimObjects/Airplanes" files?
