Order google drive files numerically?

Hi-I'm trying to numerically order files for a presentation that has both doc and sheets file type. Even though I number them in the way I want, the drive separates sheets from docs. so my folder looks like this. 6,8,1,2,3,4,5,7---6&8 being sheets and the rest docs? Any advice? Thank you. not sure how the flairs work, sorry
