But this would lead to files from the first of any month and any year to be bunched together.

I prefer classifaction in descending order… Narrow down the yearx then the month then the day then the hour then the seconds. Absolutely nobody wants seconds first then minutes

It might make sense but that doesn’t make it better

I prefer large to small imo, plus computers prefer yy mm dd too

Ah, but the month number set is smaller than the day number set. It makes just as much sense to order by sets.

Plus, starting with the month gives you time to remember what day it is without having to sit there awkwardly.
