The only safe way I've found is to call
'GetShortPathName()' and 'GetLongPathNameA()'
to get the true correct casing:
  https://github.com/gvanem/EnvTool/blob/master/src/get_file_assoc.c#L165

Works fine if the file is not already on 8.3 SFN form.

Or perhaps 'SHGetFileInfoA()' with the 'SHGFI_DISPLAYNAME' flag.
