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