What is a DOCX file?
A DOCX file is a document created by Microsoft Word or another word processing program, such as OpenOffice Writer or Apple Pages. It contains formatted text but may also include images, tables, charts, and other document elements. DOCX files are widely used in home, academic, and business environments for letters, resumes, invitations, newsletters, and other documents.
The Microsoft Word Open XML Document format was introduced with the release of Microsoft Word 2007. Since the introduction of the format, DOCX files have become one of the most common file types for saving text documents.
With the release of Word 2007, DOCX files replaced .DOC files as the standard file for saving documents in Word. Unlike DOC files, which store document data in a single binary file, DOCX files are saved in the Open XML format, which stores data as separate files and folders in a compressed Zip package. Within a DOCX file are XML files and three folders, docProps, Word, and _rels, which hold the document properties, content, and relationships between the files.
The Open XML format is designed to make document content more open and accessible. For example, document text is saved in plain text files and document images are stored as individual image files, such as .JPG or .PNG, within the DOCX file. The contained files may also include page formatting information, authorship data, and document review notes.
NOTE: To explore the contents of a DOCX file, rename the .docx extension to .zip and then decompress the resulting file with any Zip decompression utility.

How do I open a DOCX file?
You can open DOCX files with Microsoft Word for Windows or with Microsoft Word for Mac. Word is the best option for opening DOCX files because it fully supports the formatting of Word documents, which includes images, charts, tables, and text spacing and alignment. Word is also available for Android and iOS devices.
You can also open DOCX files with other word processors but some of the formatting of the original documents may be lost. Alternative word processors that support DOCX files include Corel WordPerfect (Windows), Apple Pages (Mac), and Apache OpenOffice Writer (multiplatform).
You can also open DOCX files with various web programs. Google Docs is a free web application that allows you to upload a DOCX file and view, edit, save, and convert the document.
