About formats

DOCX is the default document format for Microsoft Word since Office 2007, based on the Office Open XML (OOXML) standard published as ECMA-376 and adopted as ISO/IEC 29500. A DOCX file is a ZIP archive containing XML documents that describe the document body (document.xml), styles, themes, headers, footers, footnotes, comments, numbering definitions, and relationships between parts. Media assets like images and embedded objects reside in dedicated directories within the package. The XML structure means document content is human-inspectable and programmable — developers can create, modify, and extract content from DOCX files using standard XML libraries in any programming language without requiring Word. One significant advantage is openness and interoperability: the published specification enables any software to implement DOCX support, and the format is read and written by LibreOffice, Google Docs, Apple Pages, and dozens of other tools across all platforms. Built-in ZIP compression is another practical strength — DOCX files are substantially smaller than equivalent DOC files, and the modular XML structure improves crash recovery since corruption in one part does not necessarily destroy the entire document. The format supports all modern Word capabilities including SmartArt, content controls, bibliography management, accessibility metadata, and real-time co-authoring. DOCX has become the universal standard for document interchange in business, education, and government.

ICO is the icon file format for Microsoft Windows), introduced with Windows 1.0 in 1985 and serving as the standard container for application icons, file type icons, and shortcut icons throughout the Windows ecosystem. An ICO file bundles multiple image variants within a single container — each at different sizes (16x16, 32x32, 48x48, 256x256, and others) and color depths (4-bit, 8-bit, 24-bit, 32-bit with alpha) — allowing Windows to select the most appropriate image for each display context, from tiny taskbar buttons to large desktop icons. The container structure consists of an ICONDIR header, an array of ICONDIRENTRY records describing each variant, and the image data itself. Since Windows Vista, ICO files support embedded PNG-compressed images for the larger sizes (typically 256x256), dramatically reducing file size while maintaining quality with full alpha transparency. One advantage is automatic size adaptation — Windows pulls the optimal resolution from the ICO container for each context (Explorer list view, desktop tile, Alt-Tab preview), ensuring crisp display without the application managing separate image files. The format's operating system-level integration is another core strength: ICO files serve as the identity mechanism for executables, file associations, and shortcuts across all Windows versions, and web browsers use favicon.ico for website identity in tabs and bookmarks. ICO creation and editing is supported by image editors like GIMP, Inkscape, and dedicated icon tools, and the format remains essential for Windows application development.
