Brief about DOC and DOCX Formats

In simple terms, DOC is a proprietary format of Microsoft that is used to save Word documents. This format was in use in MS Word 2003 and all older versions like MS DOS. On the contrary, DOCX is the default file type for MS Word 2007 and its all newer versions till now. The additional X in DOCX denotes Office Open XML standard. It means that this is not a proprietary format anymore.

More about DOC File: The history of DOC file goes 30 years back when it was released for the first time for MS DOS Word. The format was designed to be proprietary and only MS Word was capable of opening this file type. Though some competing applications unofficially supported this file type, they did not support the interesting options and formatting of DOC file. Thus, it helped Microsoft to keep its dominance in the field of Word processing applications. This went on till 2006 when Microsoft officially made this format open.

More about DOCX File: The DOCX file was introduced in 2007 version of MS Word. Actually, this was the mounting pressure from its competitor Open Office and its ODF format that forced Microsoft to develop this open standard file type. DOCX is developed based on XML or Extensible Markup Language, hence getting its name Office Open XML. This file offered multiple benefits compared to DOC file. Contrary to the belief of many people, Word 2003 can read DOCX file and compatibility updates were provided to the other versions. However, many users initially went on to save their Word documents in DOC format for compatibility, but it was only compatible with Word 2003 and lower versions, not with other open-source write applications.
