The READ_FILE_USN_DATA structure specifies the versions of the update sequence number (USN) change journal supported by the caller. This structure is the input structure to the FSCTL_READ_FILE_USN_DATA control code.
MinMajorVersionThe lowest version of the USN change journal accepted by the application. If the input buffer is not specified this defaults to 2.
MaxMajorVersionThe highest version of the USN change journal accepted by the application. If the input buffer is not specified this defaults to 2. To support 128-bit file identifiers used by ReFS this must be 3 or higher.
