ok. unfortunately i forgot most of my knowledge from the old days of
ms-dos but what i can say even without it is this -- it's not about
windows explorer only. i can see the correct file names in all
applications (under windows of course), i believe. and if windows knows
whether there should be an "A" or "a" then why freebsd cannot?

ps: and, btw, how freebsd knows there's a capital A in "A.txt~" ?
because it's stored on the filesystem in that way, i guess. being
case-insensitive doesn't (necessarily) mean a FS doesn't keep a case, imho.
