Exceptions, if any, are noted in this section. If an update version, service pack or Knowledge Base (KB) number appears with a product name, the behavior changed in that update. The new behavior also applies to subsequent updates unless otherwise specified. If a product edition appears with the product version, behavior is different in that product edition.
Unless otherwise specified, any statement of optional behavior in this specification that is prescribed using the terms "SHOULD" or "SHOULD NOT" implies product behavior in accordance with the SHOULD or SHOULD NOT prescription. Unless otherwise specified, the term "MAY" implies that the product does not follow the prescription.
<1> Section 2.2: For all Windows versions except Windows 98 and Windows Millennium Edition, the Header Transaction Signature Number can be nonzero if a compound file is opened and saved with the STGM_TRANSACTED flag used in one of the following APIs: StgOpenStorage, StgCreateDocfile, StgOpenStorageEx, StgCreateStorageEx. For more information about this flag and the APIs, see [MSDN-STGMC].
<2> Section 2.6.1: When Windows sets the modified time of a root storage, it sets the modified time of the file in the file system (as described in section 2.6.2) and also sets the modified time in the root storage directory entry. When Windows retrieves the modified time of a root storage, it gets the modified time of the file in the file system but ignores the modified time in the root storage directory entry.
<3> Section 2.6.4: For Windows XP and Windows Server 2003, the compound file implementation conforms to the Unicode 3.0.1 Default Case Conversion Algorithm, simple case folding [UNICODE3.0.1], with the following exceptions.
