  41  * Win32 Shell Folders
  42  * <P>
  43  * <BR>
  44  * There are two fundamental types of shell folders : file system folders
  45  * and non-file system folders.  File system folders are relatively easy
  46  * to deal with.  Non-file system folders are items such as My Computer,
  47  * Network Neighborhood, and the desktop.  Some of these non-file system
  48  * folders have special values and properties.
  49  * <P>
  50  * <BR>
  51  * Win32 keeps two basic data structures for shell folders.  The first
  52  * of these is called an ITEMIDLIST.  Usually a pointer, called an
  53  * LPITEMIDLIST, or more frequently just "PIDL".  This structure holds
  54  * a series of identifiers and can be either relative to the desktop
  55  * (an absolute PIDL), or relative to the shell folder that contains them.
  56  * Some Win32 functions can take absolute or relative PIDL values, and
  57  * others can only accept relative values.
  58  * <BR>
  59  * The second data structure is an IShellFolder COM interface.  Using
  60  * this interface, one can enumerate the relative PIDLs in a shell
  61  * folder, get attributes, etc.
  62  * <BR>
  63  * All Win32ShellFolder2 objects which are folder types (even non-file
  64  * system folders) contain an IShellFolder object. Files are named in
  65  * directories via relative PIDLs.
