Custom Object Format GUIDs for the MTP Class Driver
Microsoft supplies a class driver for Media Transfer Protocol (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 appears as the following GUID:
{B0010000-AE6C-4804-98BA-C57B46965FE7}
A WPD application can use a content type to query an MTP driver for supported formats. If a given content type is supported, the driver should return the extended value for WPD_OBJECT_FORMAT_UNSPECIFIED_GUID.
Custom Object Format GUIDs for non-MTP Device Drivers
In addition to the object format GUIDs listed previously, device driver vendors may support private format codes. If you support private format codes, you must publish the entire GUID for your custom formats.
