Not true. Explorer displays the "long file name", which may have any
case. There's no requirement that the first letter be capitalized,
and in fact most of my own files aren't named that way and appear
with lowercase letters on my system.

I believe there is a registry setting that causes explorer to init-
cap file names when you first create them (and this may even be the
default?), but you can always go back and change the case later even
with this setting.
