Detailed explanation-1: -Microsoft Word 2010 uses the . docx file extension to save documents. However, a document that has the . docx file extension isn’t necessarily a Word 2010 document; it may also be a Word 2007 document as that is the extension used by that release of Word.

Detailed explanation-2: -The default file format for Word 2010 is Office Open XML (DOCX).

Detailed explanation-3: -If you are using Microsoft Office Word 2007 or Word 2010, you can open . docx or . docm files that were created in Word 2016 and 2013.

Detailed explanation-4: -Doc is the older version of a Microsoft Word Document. DocX is the newer version, form versions of Microsoft Word 2007 onwards. Now before you jump in thinking that the added X makes the document extreme or better in some way, that X on the end just stands for ‘Office Open XML’.
