About formats

AFF (Acorn Draw) is a vector graphics file format native to Acorn Computers' RISC OS operating system, introduced with the Draw application bundled in RISC OS 2 in April 1989. The Draw application shipped as a standard component of every RISC OS installation, providing users with a capable vector illustration tool at no additional cost. AFF files store vector objects as a sequence of tagged data blocks, each containing object type, bounding box, and type-specific data — supported objects include paths with straight lines and Bezier curves, text objects with font references, sprite (bitmap) objects, groups, and tagged objects for application-specific extensions. Path objects use cubic Bezier curves with move, line, and curve elements, supporting variable line widths, join styles, dash patterns, and flat color fills. The coordinate system uses RISC OS draw units at 1/180 inch resolution, providing precision for both screen display and print output. One advantage is the straightforward binary structure — the tagged block architecture makes AFF files simple to parse and generate programmatically. Native operating system integration is another strength: RISC OS renders Draw files natively in its desktop environment, treating vector graphics as first-class objects alongside bitmaps. While Acorn Computers ceased operations in the late 1990s, RISC OS continues under active open-source development, and AFF files remain supported through the platform's drawing applications and conversion utilities.

DOTX is the Open XML template format for Microsoft Word, introduced with Office 2007. A DOTX file is a ZIP archive containing XML parts that define document styles, page layout defaults, theme colors, theme fonts, numbering formats, boilerplate content, headers, footers, and other elements that establish a reusable document foundation. When applied, a DOTX template creates a new DOCX document inheriting the template's complete formatting system. The XML-based structure provides advantages over the legacy DOT format: templates can be inspected and modified using standard XML tools, individual components (styles, themes) are cleanly separated into dedicated files, and ZIP compression yields smaller file sizes. One advantage is modular design management — DOTX templates encapsulate a complete formatting identity as a distributable package, and the XML architecture makes it straightforward to update specific elements like color schemes or font definitions without rebuilding the entire template. Broad compatibility is another strength: DOTX templates work in Word on Windows and macOS, LibreOffice Writer, and online platforms including Google Docs (with conversion). The format integrates with Word's template management system and organizational template libraries via SharePoint, enabling centralized document governance across large teams. DOTX has become the standard for distributing document formatting frameworks in corporate, academic, and publishing environments.
