When I render one (1) RT instrument track as a wav file, two (2) wav files are created, and sometimes, not always, the file sizes are different (doubled). I'm guessing it has to do with merging one into/with an audio track (?), but that's not a setting I ever change.

Is there an advantage to using the larger file in my DAW mix, or are they identical in sound quality?

(And why can I not figure out how to attach a jpg in these posts? The directions I find are 1, supply the URL, or 2, attach using the "Enter and Image" button, but that just asks me for the URL. Help?)
