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 not only textual information, but also numerous images, graphics, scripts, 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 fairly 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. Files in this format are opened by any, including modern versions of the Word editor or its analogues 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, but 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 are able to contain data about the merge, so that the word processing template can be used together with the table or database.

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.

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.
