case-sensitivity of Mma & case-insensitity w/ Windows & DOS

I've run into a problem using ReadList[].  I think it would also happen with
other Mma functions that attempt to import or export data. I'm running Mma
2.2 under Windows 3.1.  Windows shows all files and directories (regardless
of how it was typed in) in lower case.  DOS shows everything in upper case.
I have discovered, however, that ReadList["c:\data\file1"] expects precisely
that, and is not interchangeable with ReadList["c:\data\File1"] or
ReadList["c:\Data\file1"] for
instance. Now under DOS or Windows, one can't tell what case was used when
the file or directory was created, so I'm reduced to guessing which letters
of the directory and file name should be in upper case.  Has anyone else run
into this problem?  Is there a way to get Windows to show the case of
directories or files as they were actually entered?   Many thanks in
advance!!! - J.P. Purswell
