Custom Object Format GUIDs for non-MTP Device Drivers
In addition to the object format GUIDs listed above, device driver vendors may support private format codes If they do, they must publish the entire GUID for their custom formats
Custom Object Format GUIDs for the MTP Class Driver
Microsoft supplies a class driver for MTP devices If an MTP device supports vendor-specific formats, the device vendor can extend the WPD_OBJECT_FORMAT_UNSPECIFIED GUID with a custom format code of type UINT16
For example, a vendor-extended format code of 0xB001 will appear as the following GUID:
{B0010000-AE6C-4804-98BA-C57B46965FE7}
A WPD application uses a content type to query an MTP driver for supported formats If a given content type is supported, the driver returns the extended value for WPD_OBJECT_FORMAT_UNSPECIFIED_GUID
Device Services Object Format GUIDs
A device service may optionally define additional format GUIDs These are found in the header file for each device service (eg ContactsDeviceServiceh)
