The problem may not be 'kids'. I remember when my dad retired I had a look
at his work machine.
Everything he'd done for the previous ten years or so was in *one*
enormous directory. He'd noticed things were getting 'rather slow'...
This is how a lot of non-computer-people seem to organise things. Just
save it on the desktop until we run out of room... though the user
interface calls them 'folders' (yuck), they don't actually act enough like
real file folders for people to realise how they can be used without
(Of course 'non-computer-people' are literally a dying breed these days.
Pretty much everyone under the age of 30 probably understands how
hierarchical directories are used, at least to some extent.)
