I'm trying to figure out if there is any rhyme or reason to the filenames produced when you push and hold MENU on the G3X Touch to take a screenshot. Today's filename is 4821.bmp but in ascending order the dates of my screenshots are 8/2/21, 8/7/21, 9/17/21, 8/3/21. And the filenames are all over the place, not even consistently the same number of digits.
