Well.. it does and it doesn't or to put it another way, it can but not necessarily
If you have loads of lines in the cfg (like Vancouvers example) and all are active, that is, not remmed out, then FSX can see them all and will trawl through the lot before it loads in the 'Select Aircraft' window and what you'll see in the window is all the aircraft contained therein. But.. if you have all of those folders chocka block with models and you don't want them all active at the same time, by remming the cfg lines out, FS can't see them and your 'Select Aircraft' choice will be faster as it will only load the active lines It's as much to do with housekeeping as anything else mate. By having multiple folders, you can keep stuff where YOU want it to be rather than have a single, overgrown folder as was the case in FS9. My workaround there was to have 2 additional folders outside FS.. FS Active and FS inactive and to see or not see stuff 'in sim' I'd drag aircraft out of the 'Aircraft' folder and drop them into either of the 2. FSX allows you to control what you see in a much more elegant fashion
