<1> Section 2.2.1:  The operating systems Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, Windows 8.1, and Windows Server 2012 R2 append four bytes to the end of clipboard PDUs. These four bytes are not included in the PDU size specified by the dataLen field and can be ignored.

<2> Section 3.1.1.2: On Windows-based systems, the file list is encapsulated in a "File Group Descriptor" (for more information, see [MSDN-SHELLCLIP], "CFSTR_FILEDESCRIPTOR") generic data format. This format consists of an array of File Descriptors, each of which describes a single file in a collection. The Format Name of the File Group Descriptor format is "FileGroupDescriptorW" if the descriptor is in Unicode format; otherwise, it is "FileGroupDescriptor". The Clipboard Format ID is assigned dynamically and is not constant across computer systems.
