Opening DOCX files

Did your computer fail to open a DOCX file? We explain what DOCX files are and recommend software that we know can open or convert your DOCX files.

What is a DOCX 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 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, although some open-source software applications (such as Open Office) are able to open the documents that are saved with the .docx file extension.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
