Great, thanks, yes that is it. Weird that it seems to be the default
for that, and only that folder. Personally I find when I
downloaded something one of the least interesting things about it,
and if I do care the tooltip popup has the created / modified /
accessed times in it so I can find out very easily indeed. If you do
want the folder sorted into date order so the newest stuff is at the
top that's also functionality that has been available for years. So
a completely useless and annoying feature then, put in presumably
solely because that is the way Windows 10 does it. Ugh!
Still, now I found out how to turn it off I am happy again.
