Information about the .docx (docx) file type

Below is all the information we have available on file about the .docx (docx) file type.

.docx
Microsoft Word (XML) document, generated with Microsoft Word 2007 (or later) that is saved in XML format.

The file is actually a set of XML files that are compressed. The individual XML files can be viewed by renaming the .docx file to .zip and treating it as a .zip file.

It is possible to open .docx files using earlier versions of Microsoft Word, but to do this you need the Microsoft Office Compatibility Pack. The Microsoft Office Compatibility pack is available from www.microsoft.com/downloads/details.aspx?FamilyId=941B3470-3AE9-4AEE-8F43-C6BB74CD1466&displaylang=en.

Earlier version of Microsoft Word (i.e. before Word 2007) saved documents using the .doc file extension.
