IShellFolder3

IID_IShellFolder3 {2EC06C64-1296-4F53-89E5-ECCE4EFC2189}

The IShellFolder3 methods are (as ordered in the virtual function table after the IShellFolder2 methods):

Offset Method
0x50 CreateFilteredIDList
0x54 GetFilteredIDListType
0x58 ModifyFilteredIDList
0x5C ReparentFilteredIDList
0x60 CreateStackedIDList
0x64 GetStackedKey
0x68 EnumObjectsEx
0x6C GetConditions
0x70 GetAutoListFlags

with prototypes:

HRESULT CreateFilteredIDList (IFilterCondition *, FILTERIDLISTTYPE, IPropertyStore *, PITEMID_CHILD *);
HRESULT GetFilteredIDListType (PCITEMID_CHILD, FILTERIDLISTTYPE *);
HRESULT ModifyFilteredIDList (PCITEMID_CHILD, IFilterCondition *, PITEMID_CHILD *);
HRESULT ReparentFilteredIDList (PCIDLIST_RELATIVE, PIDLIST_RELATIVE *);
HRESULT CreateStackedIDList (PROPERTYKEY const &, PIDLIST_ABSOLUTE *);
HRESULT GetStackedKey (PROPERTYKEY *);
HRESULT EnumObjectsEx (HWND, IBindCtx *, ULONG, IItemFilter *, IEnumIDList **);
HRESULT GetConditions (PROPERTYKEY const &, IQueryUnit *, REFIID, PVOID *);
HRESULT GetAutoListFlags (ULONG *);

in which IFilterCondition, IItemFilter and IQueryUnit are undocumented interfaces and FILTERIDLISTTYPE is invented as a typedef for an undocumented enumeration:

typedef enum tagFILTERIDLISTTYPE FILTERIDLISTTYPE;

Implementations

The only known implementations are in SHELL32.DLL and TWEXT.DLL from Windows Vista, for the creatable classes:

CLSID_DBFolder {B2952B16-0E07-4E5A-B993-58C52CB94CAE} shell32.dll
CLSID_TimeWarpFolder {9DB7A13C-F208-4981-8353-73CC61AE2783} twext.dll

Neither is documented.
