What is a DOCX file?
A .DOCX file is a Microsoft Word Open XML Format document file.
The .docx extension is assigned to Microsoft Word documents created in the 2007 edition of Microsoft Word (and all later editions). This is a new Word format that is based on XML, which allows for better compression of Word documents and reduced file sizes. The difference between the XML Word format and prior Word formats is that XML Word documents are saved in a text format instead of the older binary format.
The DOCX format is known as the Microsoft Office Open XML format. Documents that are saved in .docx format are not compatible with older versions of Microsoft Word. However, some open-source software applications (such as Open Office) can open the saved documents with the .docx file extension.
