Microsoft Word Document

File extension	.doc
File category	documents
Description	DOC – is a special extension corresponding to the documents created in the text editor Microsoft World, up to the 2007 version. This format stores information about the formatting of a text document - paragraphs, lists, indents, alignments, and much more. Microsoft Word DOC files can include textual information and numerous images, graphics, scripts, and diagrams. DOC is an extension in the binary file format, which begins with an information block that acts as a key element of the entire collection of data files. Such binary files include a relatively large amount of information about the formatting of a text document. Traditionally, the extension has become widespread for creating text-format documents in a wide range of OS. In this format, files are opened by any, including modern versions of the Word editor or its analogs from free packages like Open Office, Libre Office, or utilities like Corel WordPerfect.
Technical details	The first versions of the DOC file format prioritized the content of the formatted text. Still, over time, a large number of built-in objects were added to it, among which both diagrams and graphs are found, as well as various media files (sounds, video). Files with the DOC extension can contain data about the merge so that the word processing template can be used together with the table or database.

File category	documents
Description	DOCX – is a standard extension that includes the test content of the document, pictures, painted objects, styles, and other elements.

The format allows you to work with different content based on many tools that automate the creation and editing processes. For the correct display of the DOCX files in obsolete versions of Word, you need to install a special compatibility package. It helps to convert text content to DOC format.
Technical details	The DOCX extension is written in XML markup language and includes many document elements stored as separate files combined into one archived ZIP file. The appearance of such a format confirms the transition of Microsoft Office suite software solutions to the Open XML international standard. Therefore, the extension is supported by many open source applications, for example, LibreOffice Writer and OpenOffice Writer.
