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 | |
