  13    Here are brief descriptions of the filename formats supported by this class:
  14
  15    wxPATH_UNIX: standard Unix format, used under Darwin as well, absolute file
  16                 names have the form:
  17                 /dir1/dir2/.../dirN/filename, "." and ".." stand for the
  18                 current and parent directory respectively, "~" is parsed as the
  19                 user HOME and "~username" as the HOME of that user
  20
  21    wxPATH_DOS:  DOS/Windows format, absolute file names have the form:
  22                 drive:\dir1\dir2\...\dirN\filename.ext where drive is a single
  23                 letter. "." and ".." as for Unix but no "~".
  24
  25                 There are also UNC names of the form \\share\fullpath and
  26                 MSW unique volume names of the form \\?\Volume{GUID}\fullpath.
  27
  28                 The latter provide a uniform way to access a volume regardless of
  29                 its current mount point, i.e. you can change a volume's mount
  30                 point from D: to E:, or even remove it, and still be able to
  31                 access it through its unique volume name. More on the subject can
  32                 be found in MSDN's article "Naming a Volume" that is currently at
  33                 http://msdn.microsoft.com/en-us/library/aa365248(VS.85).aspx.
  34
  35
  36    wxPATH_MAC:  Mac OS 8/9 only, not used any longer, absolute file
  37                 names have the form
  38                     volume:dir1:...:dirN:filename
  39                 and the relative file names are either
  40                     :dir1:...:dirN:filename
  41                 or just
  42                     filename
  43                 (although :filename works as well).
  44                 Since the volume is just part of the file path, it is not
  45                 treated like a separate entity as it is done under DOS and
  46                 VMS, it is just treated as another dir.
  47
  48    wxPATH_VMS:  VMS native format, absolute file names have the form
  49                     <device>:[dir1.dir2.dir3]file.txt
  50                 or
  51                     <device>:[000000.dir1.dir2.dir3]file.txt
  52
  53                 the <device> is the physical device (i.e. disk). 000000 is the
  54                 root directory on the device which can be omitted.
  55
  56                 Note that VMS uses different separators unlike Unix:
  57                  : always after the device. If the path does not contain : than
  58                    the default (the device of the current directory) is assumed.
  59                  [ start of directory specification
  60                  . separator between directory and subdirectory
  61                  ] between directory and file
