I have at least 1500 Aircraft for my FSX Gold / Acceleration Boxed edition
I too decided that there were too many AIRCRAFT and Extra Aircraft Textures in my FSX Sim and it was "slowing" load times considerably,
So, I decided to create an "EXTRA HANGER" to store just the "AIRCRAFT" in, and leave all the gauges files and Effects files in the sim.
Tho I also copied & back up all those files in the Extra Hanger too !! in a separate folder within the Extra Hanger !!
Along with tons of my Freeware & Payware scenery and their installers if they had any.
So,,,,,,,,,, I spent some time "Pre-Organizing" the Hanger inside with Folders by certain names
for example :
FSX Extra Aircraft
FSX Gauges
FSX Effects
New Paint textures to install
Freeware Scenery
PAYWARE Scenery
Payware Aircraft
Freeware Aircraft
Propliners
Jetliners
All those listed above are separate Folders I made in my "External Hanger" !!!
Organization is prudent !!
that way your "Organized" and NOT cluttered and ya' won't spend excess time trying to find where ya' stuffed what Aircraft or texture in your "External Hanger" !!
I find that having the "External Hanger" is a must if you have a lot of ADD-ON Aircraft and ADD ON Scenery !!!
Sure ended a lot of frustration, and mental fatigue trying to resolve problems with the sim.
I now only keep about 25 to 30 Aircraft in the actual FSX Sim at any one time, when I'm done with them, I just delete the aircraft out of the FSX Sim Objects Airplanes folder , NO Problem, because I've got them backed up in the "External Hanger" , to reuse and copy & paste back into the Main FSX Aircraft folder at any time !!
having 1500 to 2000 Aircraft and all the textures, gauges, effects along with all the add on sceneries is overload ,,,,,,
I decided to purchase the TOSHIBA External Hard Drive Storage to use as my "External Hanger", I also keep some Aircraft back up on CD/DVD Disks as well.
Below is a photo of the TOSHIBA External Hard Drive I use as the " External Hanger" !!
The 2nd Photo is of 1 of my actual Sim Hangers with a Hott Female Security Guard watching over all of my Extra Aircraft !!
