13 Here are brief descriptions of the filename formats supported by this class:
15 wxPATH_UNIX: standard Unix format, absolute file names have the form
16 /dir1/dir2/.../dirN/filename, "." and ".." stand for the
17 current and parent directory respectively, "~" is parsed as the
18 user HOME and "~username" as the HOME of that user
20 wxPATH_DOS: DOS/Windows format, absolute file names have the form
21 drive:\dir1\dir2\...\dirN\filename.ext where drive is a single
22 letter. "." and ".." as for Unix but no "~".
24 There are also UNC names of the form \\share\fullpath
26 wxPATH_MAC: Mac OS 8/9 format, absolute file names have the form
27 volume:dir1:...:dirN:filename
28 and the relative file names are either
29 :dir1:...:dirN:filename
32 (although :filename works as well).
34 wxPATH_VMS: VMS native format, absolute file names have the form
35 <device>:[dir1.dir2.dir3]file.txt
37 <device>:[000000.dir1.dir2.dir3]file.txt
39 the <device> is the physical device (i.e. disk). 000000 is the
40 root directory on the device which can be omitted.
42 Note that VMS uses different separators unlike Unix:
43 : always after the device. If the path does not contain : than
44 the default (the device of the current directory) is assumed.
45 [ start of directory specyfication
46 . separator between directory and subdirectory
47 ] between directory and file
