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
26
27 wxPATH_MAC: Mac OS 8/9 and Mac OS X under CodeWarrior 7 format, absolute file
28 names have the form
29 volume:dir1:...:dirN:filename
30 and the relative file names are either
31 :dir1:...:dirN:filename
32 or just
33 filename
34 (although :filename works as well).
35 Since the volume is just part of the file path, it is not
36 treated like a separate entity as it is done under DOS and
37 VMS, it is just treated as another dir.
38
39 wxPATH_VMS: VMS native format, absolute file names have the form
40 <device>:[dir1.dir2.dir3]file.txt
41 or
42 <device>:[000000.dir1.dir2.dir3]file.txt
43
44 the <device> is the physical device (i.e. disk). 000000 is the
45 root directory on the device which can be omitted.
46
47 Note that VMS uses different separators unlike Unix:
48 : always after the device. If the path does not contain : than
49 the default (the device of the current directory) is assumed.
50 [ start of directory specyfication
51 . separator between directory and subdirectory
52 ] between directory and file
