22  * As you know, windows and unix do have a different philosophy with regard to
23  * the question of how a filesystem should be laid out. While we unix geeks
24  * learned to love the 'one-tree-rooted-at-/' approach, windows has in fact
25  * a whole forest of filesystem trees, each of which is typically identified by
26  * a drive letter.
27  *
28  * We would like wine to integrate as smoothly as possible (that is without
29  * sacrificing win32 compatibility) into the unix environment. For the
30  * filesystem question, this means we really would like those windows
31  * applications to work with unix path- and file-names. Unfortunately, this
32  * seems to be impossible in general. Therefore we have those symbolic links
33  * in wine's 'dosdevices' directory, which are used to simulate drives
34  * to keep windows applications happy. And as a consequence, we have those
35  * drive letters show up now and then in GUI applications running under wine,
36  * which gets the unix hardcore fans all angry, shouting at us @#!&$%* wine
37  * hackers that we are seducing the big companies not to port their applications
38  * to unix.
39  *
40  * DOS paths do appear at various places in GUI applications. Sometimes, they
41  * show up in the title bar of an application's window. They tend to accumulate
42  * in the most-recently-used section of the file-menu. And I've even seen some
43  * in a configuration dialog's edit control. In those examples, wine can't do a
44  * lot about this, since path-names can't be told apart from ordinary strings
45  * here. That's different in the file dialogs, though.
46  *
47  * With the introduction of the 'shell' in win32, Microsoft established an 
48  * abstraction layer on top of the filesystem, called the shell namespace (I was
49  * told that Gnome's virtual filesystem is conceptually similar). In the shell
50  * namespace, one doesn't use ascii- or unicode-strings to uniquely identify
51  * objects. Instead Microsoft introduced item-identifier-lists (The c type is 
52  * called ITEMIDLIST) as an abstraction of path-names. As you probably would
53  * have guessed, an item-identifier-list is a list of item-identifiers (whose
54  * c type's funny name is SHITEMID), which are opaque binary objects. This means
55  * that no application (apart from Microsoft Office) should make any assumptions
56  * on the internal structure of these SHITEMIDs. 
57  *
58  * Since the user prefers to be presented the good-old DOS file-names instead of 
59  * binary ITEMIDLISTs, a translation method between string-based file-names and
60  * ITEMIDLISTs was established. At the core of this are the COM-Interface
61  * IShellFolder and especially it's methods ParseDisplayName and 
62  * GetDisplayNameOf. Basically, you give a DOS-path (let's say C:\windows) to
63  * ParseDisplayName and get a SHITEMID similar to <Desktop|My Computer|C:|windows|>.
64  * Since it's opaque, you can't see the 'C', the 'windows' and the other stuff.
65  * You can only figure out that the ITEMIDLIST is composed of four SHITEMIDS.
66  * The file dialog applies IShellFolder's BindToObject method to bind to each of
67  * those four objects (Desktop, My Computer, C: and windows. All of them have to 
68  * implement the IShellFolder interface.) and asks them how they would like to be 
69  * displayed (basically their icon and the string displayed). If the file dialog 
70  * asks <Desktop|My Computer|C:|windows> which sub-objects it contains (via 
71  * EnumObjects) it gets a list of opaque SHITEMIDs, which can be concatenated to 
72  * <Desktop|...|windows> to build a new ITEMIDLIST and browse, for instance, 
73  * into <system32>. This means the file dialog browses the shell namespace by 
74  * identifying objects via ITEMIDLISTs. Once the user has selected a location to 
75  * save his valuable file, the file dialog calls IShellFolder's GetDisplayNameOf
76  * method to translate the ITEMIDLIST back to a DOS filename.
77  * 
78  * It seems that one intention of the shell namespace concept was to make it 
79  * possible to have objects in the namespace, which don't have any counterpart 
80  * in the filesystem. The 'My Computer' shell folder object is one instance
81  * which comes to mind (Go try to save a file into 'My Computer' on windows.)
82  * So, to make matters a little more complex, before the file dialog asks a
83  * shell namespace object for it's DOS path, it asks if it actually has one.
84  * This is done via the IShellFolder::GetAttributesOf method, which sets the
85  * SFGAO_FILESYSTEM if - and only if - it has.
86  *
87  * The two things, described in the previous two paragraphs, are what unixfs is
88  * based on. So basically, if UnixDosFolder's ParseDisplayName method is called 
89  * with a 'c:\windows' path-name, it doesn't return an 
90  * <Desktop|My Computer|C:|windows|> ITEMIDLIST. Instead, it uses 
91  * shell32's wine_get_unix_path_name and the _posix_ (which means not the win32) 
92  * fileio api's to figure out that c: is mapped to - let's say - 
93  * /home/mjung/.wine/drive_c and then constructs a 
94  * <Desktop|/|home|mjung|.wine|drive_c> ITEMIDLIST. Which is what the file 
95  * dialog uses to display the folder and file objects, which is why you see a 
96  * unix path. When the user has found a nice place for his file and hits the
97  * save button, the ITEMIDLIST of the selected folder object is passed to 
98  * GetDisplayNameOf, which returns a _DOS_ path name 
99  * (like H:\home_of_my_new_file out of <|Desktop|/|home|mjung|home_of_my_new_file|>).
100  * Unixfs basically mounts your dos devices together in order to construct
101  * a copy of your unix filesystem structure.
102  *
103  * But what if none of the symbolic links in 'dosdevices' points to '/', you 
104  * might ask ("And I don't want wine have access to my complete hard drive, you 
105  * *%&1#!"). No problem, as I stated above, unixfs uses the _posix_ apis to 
106  * construct the ITEMIDLISTs. Folders, which aren't accessible via a drive letter,
107  * don't have the SFGAO_FILESYSTEM flag set. So the file dialogs shouldn't allow
108  * the user to select such a folder for file storage (And if it does anyhow, it 
109  * will not be able to return a valid path, since there is none). Think of those 
110  * folders as a hierarchy of 'My Computer'-like folders, which happen to be a 
111  * shadow of your unix filesystem tree. And since all of this stuff doesn't 
112  * change anything at all in wine's fileio api's, windows applications will have 
113  * no more access rights as they had before. 
114  *
115  * To sum it all up, you can still safely run wine with you root account (Just
116  * kidding, don't do it.)
117  *
118  * If you are now standing in front of your computer, shouting hotly 
119  * "I am not convinced, Mr. Rumsfeld^H^H^H^H^H^H^H^H^H^H^H^H", fire up regedit
120  * and delete HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
121  * Explorer\Desktop\Namespace\{9D20AAE8-0625-44B0-9CA7-71889C2254D9} and you 
122  * will be back in the pre-unixfs days.
