This function retrieves an instance of the subsystem object that implements IPropertyDescriptionList, to obtain either the entire list or a partial list of property descriptions in the system.
PSFormatForDisplay	Gets a formatted, Unicode string representation of a property value stored in a PROPVARIANT structure. The caller is responsible for allocating the output buffer.
PSFormatForDisplayAlloc	Gets a formatted, Unicode string representation of a property value stored in a PROPVARIANT structure. This function allocates memory for the output string.
PSFormatPropertyValue	Gets a formatted, Unicode string representation of a property value stored in a property store. This function allocates memory for the output string.
PSGetImageReferenceForValue	Gets an instance of a property description interface for a specified property.
PSGetItemPropertyHandler	Retrieves a property handler for a Shell item.
PSGetItemPropertyHandlerWithCreateObject	Retrieves a property handler for a Shell item.
PSGetNamedPropertyFromPropertyStorage	Gets a value from serialized property storage by property name.
PSGetNameFromPropertyKey	Retrieves the canonical name of the property, given its PROPERTYKEY.
PSGetPropertyDescription	Gets an instance of a property description interface for a property specified by a PROPERTYKEY structure.
PSGetPropertyDescriptionByName	Gets an instance of a property description interface for a specified property name.
PSGetPropertyDescriptionListFromString	Gets an instance of a property description list interface for a specified property list.
PSGetPropertyFromPropertyStorage	Gets the value of a property as stored in serialized property storage.
PSGetPropertyKeyFromName	Gets the property key for a canonical property name.
PSGetPropertySystem	Gets an instance of the subsystem object that implements IPropertySystem.
PSGetPropertyValue	Gets a property value from a property store.
PSLookupPropertyHandlerCLSID	Gets the class identifier (CLSID) of a per-computer, registered file property handler.
PSPropertyBag_Delete	Deletes a property from a property bag.
PSPropertyBag_ReadBOOL	Reads the BOOL data value of a property in a property bag.
PSPropertyBag_ReadBSTR	Reads a BSTR data value from a property in a property bag.
PSPropertyBag_ReadDWORD	Reads a DWORD data value from property in a property bag.
PSPropertyBag_ReadGUID	Reads the GUID data value from a property in a property bag.
PSPropertyBag_ReadInt	Reads a int data value from a property in a property bag.
PSPropertyBag_ReadLONG	Reads a long data value from a property in a property bag.
PSPropertyBag_ReadPOINTL	Retrieves the coordinates stored in a property contained in a specified property bag.
PSPropertyBag_ReadPOINTS	Retrieves the coordinates stored in a property contained in a specified property bag.
PSPropertyBag_ReadPropertyKey	Reads the property key of a property in a specified property bag.
PSPropertyBag_ReadRECTL	Retrieves the coordinates of a rectangle stored in a property contained in a specified property bag.
PSPropertyBag_ReadSHORT	Reads the SHORT data value of a property in a property bag.
PSPropertyBag_ReadStr	Reads the string data value of a property in a property bag.
PSPropertyBag_ReadStrAlloc	Retrieves details about the allocation or releasing of memory for a string that is stored in a property contained in a specified property bag.
PSPropertyBag_ReadStream	Reads the data stream stored in a given property contained in a specified property bag.
PSPropertyBag_ReadType	Reads the type of data value of a property that is stored in a property bag.
PSPropertyBag_ReadULONGLONG	Reads a ULONGLONG data value from a property in a property bag.
PSPropertyBag_ReadUnknown	Reads a given property of an unknown data value in a property bag.
PSPropertyBag_WriteBOOL	Sets the BOOL value of a property in a property bag.
PSPropertyBag_WriteBSTR	Sets the BSTR value of a property in a property bag.
PSPropertyBag_WriteDWORD	Sets the DWORD value of a property in a property bag.
PSPropertyBag_WriteGUID	Sets the GUID value of a property in a property bag.
PSPropertyBag_WriteInt	Sets the int value of a property in a property bag.
PSPropertyBag_WriteLONG	Sets the long value of a property in a property bag.
PSPropertyBag_WritePOINTL	Stores the coordinates of a point in a property in a property bag.
PSPropertyBag_WritePOINTS	Stores the coordinates of a point in a property in a property bag.
PSPropertyBag_WritePropertyKey	Sets the property key value of a property in a property bag.
PSPropertyBag_WriteRECTL	Stores the coordinates of a rectangle in a property in a property bag.
PSPropertyBag_WriteSHORT	Sets the SHORT value of a property in a property bag.
PSPropertyBag_WriteStr	Sets the string value of a property in a property bag.

PSRegisterPropertySchema	Informs the schema subsystem of the addition of a property description schema file.
PSSetPropertyValue	Sets the value of a property in a property store.
PSStringFromPropertyKey	Creates a string that identifies a property from that property's key.
PSUnregisterPropertySchema	Informs the schema subsystem of the removal of a property description schema file.
SHAddDefaultPropertiesByExt	Adds default properties to the property store as registered for the specified file extension.
SHGetPropertyStoreForWindow	Retrieves an object that represents a specific window's collection of properties, which allows those properties to be queried or set.
SHGetPropertyStoreFromIDList	Retrieves an object that supports IPropertyStore or related interfaces from a pointer to an item identifier list (PIDL).
SHGetPropertyStoreFromParsingName	Returns a property store for an item, given a path or parsing name.
SHPropStgCreate	Ensures proper handling of code page retrieval or assignment for the requested property set operation.
SHPropStgReadMultiple	Wraps the IPropertyStorage::ReadMultiple function to ensure that ANSI and Unicode translations are handled properly for deprecated property sets.
