You got it. It didn't use to matter, but now we're trying to move to
lower case. Mostly.
It didn't use to matter -- DOS's file system is 'case-insensitive'. But
DOS always stores & returns filenames as all-caps, so most filenames
were considered to be all caps.
But within part files, it's always been somewhat customary to use
lowercase for filenames -- in fact, LEdit has a limitation that it only
recognizes stud-file references if they are lowercase. So parts that
have studs coded as STUD.DAT don't get the benefit of LEdit substituting
a line (studline.dat) for the actual studs.
When LDraw spread to other OSes, there were a few problems with
case-sensitive file systems, since there wasn't a 'standard' for the
case of filenames. There was some discussion, and it was more-or-less
agreed that the 'most-official' versions of the part file names would be
lower case.
We'll never be totally rid of upper-case names, as long as we're
distributing the parts with the DOS-based ARJ self-extracting
executables. But for the master data on the ldraw.org server, all new
submissions should be lowercase.
I'm slowly 'enhancing' the Submit function on the PT, to more carefully
enforce the various file standards. I add new checks as I have time.
