22 * DO NOT use this definitions outside the shell32.dll !
24 * The contents of a pidl should never used from a application
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.
40 * the pidl does cache fileattributes to speed up SHGetAttributes when
41 * displaying a big number of files.
43 * a pidl of NULL means the desktop
45 * The structure of the pidl seems to be a union. The first byte of the
46 * PIDLDATA desribes the type of pidl.
