21  * NOTES:
22  *
23  * DO NOT use these definitions outside the shell32.dll!
24  *
25  * The contents of a pidl should never be used directly from an application.
26  *
27  * Undocumented:
28  * MS says: the abID of SHITEMID should be treated as binary data and not
29  * be interpreted by applications. Applies to everyone but MS itself.
30  * Word95 interprets the contents of abID (Filesize/Date) so we have to go
31  * for binary compatibility here.
