What is a DOCX file?
DOCX is the modern default format for Microsoft Word documents. Introduced with Word 2007, it is based on the Office Open XML (OOXML) standard and offers better compression and data recovery than the older DOC format.
DOCX files store text, images, tables, charts, and formatting as a collection of zipped XML files. The format is supported by most modern word processors, including open-source alternatives like LibreOffice and Google Docs.
How to open DOCX files
DOCX files can be opened in Microsoft Word, Google Docs, LibreOffice, and other modern text editors. It is the most widely supported word processing format today.
