1 Introduction

This document specifies the Word Binary File Format (.doc) Structure, which defines the Word Binary File Format (.doc). The Word Binary File Format is a collection of records and structures that specify text, tables, fields, pictures, embedded XML markup, and other document content. The content can be printed on pages of multiple sizes or displayed on a variety of devices.

The Word Binary File Format begins with a master record named the File Information Block, which references all other data in the file.  By following links from the File Information Block, an application can locate all text and other objects in the file and compute the properties of those objects.

Sections 1.7 and 2 of this specification are normative. All other sections and examples in this specification are informative.
