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
