Hi all!
The other day I was working a bit on a program that can parse dat
files under linux. Now, I have my dat files, along with ldraw and
mlcad installed on a Windows partition. All the dat files that come
with the ldraw package and updates there have names with all lowercase
letters, i.e. 1234a.dat. However, in the parts.lst file, made by
mklst(?), all these names are listed as i.e. 1234A.DAT, that is, with
uppercase letters. Now, the windows filesystem knows the preferred
case of the filenames, which, in this case happens to be all
lowercase, but when opening files it is actually case-insensitive, so
you can open 1234a.dat as 1234A.DAT, or even 1234a.DaT, and it will
work.
When mounted under linux, however, this will not work. If the filename
of the file is 1234a.dat with all lowercase, you will have to open it
with all lowercase, or the file will not be found.
So far, you could say, there is no problem, as I could just convert
all the names to all lowercase, and hey, presto, all the files would
be found. However, I have also used MLCad to save MOCs as dats under
windows, and have used mixed case names there, and I'm sure eventually
there may be mixed case files directly on my linux filesystem. So
converting all the names of all the dat files I encounter to lowercase
is not an option.
Is there any chance that the mklst program could be modified to
accurately reflect the case of the files in question? I.e., if a file
is called 1234a.dat, could it be entered in the parts.lst file as
such, rather than 1234A.DAT? Or is this information perhaps not
available to pure MSDOS programs, as mklst.exe must be? (In which case
I will have to find another solution.)
Regards,
Johannes.

I believe that straight-DOS programs don't have mixed-case filename information.
A pure DOS hard-drive actually stores all filenames on the harddrive in upper
case, and MSDOS under Windows maintains upper-case-only for compatibility with
older DOS programs.

It does work, you can open either 1234a.dat or 1234A.DAT, or even 1234a.DaT.
The fat/vfat/msdos filesystem in Linux is case-insensitive.
Try it!

Pure MSDOS programs see all files in uppercase.

Ah. Thanks for the tip, that would be great.

The default behavior is to be case insensitive but you can set an
option to make it case sensitive, take a look at the man page for mount.
