   How do I detect HPFS drives in OS/2 ?
   =====================================

   The short answer, that applies to 90% of the people who ask this
   question, is not one that most people like to hear:  You don't.

   Many people equate "detect HPFS" with "determine that
long filenames
   can be used when creating files".  This is not the case.  With the
   multiplicity of filesystems available on OS/2, there are at least
   three (if not more) different filesystems that support long
   filenames: Netware, HPFS, and PC-Support.

   Yes, you can detect, via DosQueryFSAttach, whether the name of the
   filesystem driver for a drive is "HPFS", but that means that your
   program fails to use long filenames on Netware fileservers, on
   PC-Support shared folders, and on any other filesystems that may
   support long filenames, either now or in the future.

   As to detecting whether a filesystem supports long filenames, the
   only answer is to suck it and see.  Try to create a file with a
   non-8.3 filename on the drive, and see whether an error is returned
   or not.

   If, of course, the error is that the drive is read-only, or that you
   do not have the access rights to create files, you don't lose
   anything by this latter test; if you cannot create a file at all, it
   doesn't really matter whether you can save files with long filenames
   or not.
