Description | 🔵 .doc The .doc format is a proprietary document file format used by Microsoft Word, primarily in versions before Word 007. It's a binary file format for text documents that may contain rich text content, images, tables, graphs, and other elements typical of word processing documentsThe .doc format was widely used for creating and sharing documents in business and academic settings. However, it has largely been supplanted by the .docx format in more recent versions of Microsoft Word. |
Technical details | 🔵 The `.doc` format, closely tied to Microsoft Word, was a preeminent word processing standard before the `.docx` format emerged in Office 2007. It was a proprietary binary format, making its structure inaccessible for third-party software development. The format includes binary codes for displaying text, images, and formatting in Word. It comprises text, formatting details, images, and other elements, supporting various text formats. Despite being associated with Word, other processors like OpenOffice also support it, albeit with compatibility variations across different Word versions. The `.docx` format, introduced later, is based on Office Open XML, offering more efficiency with XML and ZIP compression. However, modern Word versions maintain support for `.doc` for backward compatibility, highlighting its lasting impact and relevance in digital word processing. |

Technical details | 🔵 The `.docx` format, launched with Microsoft Office 2007, replaces the older `.doc` format in Microsoft Word. It's based on the Office Open XML standard, using XML to detail document structure and content, making it more transparent and easier to process. `.docx` files are zip archives containing XML files and resources, with folders like 'word', 'docProps', and 'rels' for text, properties, and relationships. Main text is in `document.xml`, with separate files like `styles.xml` for styling and directories for embedded media. This format enhances interoperability, reduces file sizes, and improves corruption recovery. It's supported by most modern word processors, with Microsoft offering compatibility packs for older Word versions. For security, macros are in a separate `.docm` file. `.docx` is a step forward in document format technology, emphasizing openness, interoperability, and efficient data management. |
