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 will need to 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 should use a content type to query an MTP driver for supported formats. If a given content type is supported, the driver will return the extended value for WPD_OBJECT_FORMAT_UNSPECIFIED_GUID.
