Microsoft Word traditionally used DOC files for its document files before version 2007. Later versions use the DOCX file extension instead. DOC file format is obsolete and no longer developed, but still widely used due to the popularity of Microsoft Office. Newer documents are converted from doc to docx format.
The DOCX file extension is best known for its use in Microsoft Word, a powerful word processor that gives users the ability to create and share documents. Docx files feature an Open XML formatting schema for greater compatibility and ZIP compression, resulting in smaller files.
