I have a large amount of FS2004 traffic files generated with Traffic Tools. Is there any advantage from a perfomance perspective in combining some or all of them into large BGL files or is it better to leave them as individual files?Doug

I used to run with just one large .bgl for the airlines and another for GA. I have recently switched to multiple .bgl files, 405 actually, and I see no difference in performance. It is, however, much easier to install or modify flight plans when they are separate.
