About formats

DOCM is a macro-enabled document format for Microsoft Word, introduced with Office 2007 as part of the Office Open XML family. Structurally identical to DOCX — a ZIP archive containing XML parts for document content, styles, themes, and media — DOCM adds the ability to store and execute VBA (Visual Basic for Applications) macro code within the document. The separate .docm extension was a deliberate security measure: users and administrators can distinguish macro-containing files by extension alone, and group policies can restrict macro-enabled formats while allowing standard DOCX documents to open freely. DOCM files store VBA projects in a vbaProject.bin stream within the ZIP package alongside the same XML document content used by DOCX. Macros in Word documents enable automated report generation, custom form processing, document assembly from templates and data sources, and integration with external systems. One advantage is document-level automation — a DOCM file can include routines that populate content from databases, enforce formatting rules, validate fields before submission, or generate derivative documents automatically. The format preserves full compatibility with the OOXML specification, so all standard Word features — styles, tracked changes, comments, embedded media — work identically to DOCX. DOCM is supported by Microsoft Word on Windows and macOS, with macro execution limited to the desktop application.

AZW3, also known as Kindle Format 8 (KF8), is Amazon's advanced ebook format introduced in November 2011 alongside the first Kindle Fire tablet. It replaced the older MOBI-based AZW format with a substantially more capable layout engine built on HTML5 and CSS3 subsets, enabling fixed layouts, embedded fonts, SVG graphics, drop caps, and other typographic refinements that were impossible in earlier Kindle formats. Internally, an AZW3 file packages content in a structure derived from EPUB, wrapped in Amazon's proprietary Palm database container with optional DRM protection. The format supports both reflowable text for novels and fixed-layout pages for comics, cookbooks, and children's titles. One major advantage is rich formatting fidelity — publishers can produce visually sophisticated ebooks with complex page designs, nested tables, and precise font control that render consistently across the Kindle ecosystem. Another strength is backward compatibility: AZW3 files can bundle a MOBI fallback section so older Kindle hardware still displays the content, even without full KF8 rendering. The format integrates tightly with Amazon's Kindle platform, supporting features like X-Ray, Whispersync page tracking, and in-book dictionary lookups across millions of devices and apps worldwide.
