mtools: case sensitivity
2.6 Case sensitivity of the VFAT file system
============================================
The VFAT file system is able to remember the case of the filenames.
However, filenames which differ only in case are not allowed to coexist
in the same directory. For example if you store a file called
LongFileName on a VFAT file system, mdir shows this file as
LongFileName, and not as Longfilename. However, if you then try to add
LongFilename to the same directory, it is refused, because case is
ignored for clash checks.
The VFAT file system allows you to store the case of a filename in
the attribute byte, if all letters of the filename are the same case,
and if all letters of the extension are the same case too. Mtools uses
this information when displaying the files, and also to generate the
Unix filename when mcopying to a Unix directory. This may have
unexpected results when applied to files written using an pre-7.0
version of DOS: Indeed, the old style filenames map to all upper case.
This is different from the behavior of the old version of mtools which
used to generate lower case Unix filenames.
