Name: Microsoft Word for Windows
Version: 2007 onwards
Description: From Microsoft Office 2007 onwards, the core output format of MS Word has been based on the Office Open XML (OOXML) file format. The ISO standard for OOXML is ISO/IEC DIS 29500. An OOXML file format consists of a compressed zip archive that is designated according to which file type it is. Further detail on OOXML can be found within fmt/189 - Microsoft Office Open XML. An alternative extension of .wbk refers to a backup file of a Word document, however there is no material or structural difference between a .wbk file and the .doc file it is a backup of.
