This article explains more about DOCX files, including how to open them or convert them to a format compatible with other software.
What is a DOCX file?
A file with the DOCX file extension is a Microsoft Word Open XML Format Document file.
DOCX files are used for everything from resumes and cover letters to reports, flyers, documentation, invitations, newsletters, and more. These files typically contain text, but can also include objects, styles, rich formatting, and images.
Microsoft began using DOCX files in Microsoft Word starting with Word 2007, while earlier versions of Word used the DOC file extension.
