About formats

DOTM is a macro-enabled template format for Microsoft Word, introduced with Office 2007 as part of the Office Open XML family. DOTM combines the template functionality of DOTX — providing reusable styles, page layouts, boilerplate content, and formatting definitions — with the ability to embed VBA macro code that executes in documents created from the template. The format is a ZIP archive containing XML parts for styles, document defaults, and theme definitions, plus a vbaProject.bin stream for the VBA project. This combination enables organizations to distribute not just visual consistency but also functional automation: every document created from a DOTM template inherits both the formatting framework and programmatic capabilities. Common use cases include templates that auto-populate document fields from corporate directories, enforce naming conventions, generate tables of contents, insert dynamic headers with project metadata, or validate document structure before submission. One advantage is embedded workflow automation — a DOTM template can include initialization macros that configure the document environment, register custom ribbon commands, and connect to data sources the moment a new document is created from it. The distinct .dotm extension allows administrators to apply differentiated trust policies for macro-containing templates versus standard DOTX files. DOTM is supported exclusively in Microsoft Word desktop editions where VBA execution is available.

MOBI is an ebook format originally developed by Mobipocket SA, a French company founded in 2000 that was later acquired by Amazon in 2005. The format builds on the PalmDOC/PDB container structure, adding support for HTML-based content markup, embedded images, a DRM layer, and a JavaScript subset for limited interactivity. MOBI files use a record-based database architecture inherited from Palm OS, with a header structure containing metadata like title, author, publisher, and language followed by compressed HTML content records. The format became the foundation of Amazon's early Kindle ecosystem — the original AZW format used on first-generation Kindles was essentially MOBI with Amazon's own DRM wrapper. MOBI supports reflowable text with basic formatting including bold, italic, headings, lists, and tables, as well as internal hyperlinks and a built-in table of contents. One advantage is broad device compatibility: MOBI files are recognized by Kindle devices and apps spanning over a decade of hardware, as well as numerous third-party readers on desktop and mobile platforms. The format's lightweight structure is another strength — even long novels produce compact files that load quickly on modest hardware. While Amazon has since moved to the more capable AZW3/KF8 format for new publishing, MOBI remains widely circulated in existing ebook libraries and continues to be produced by conversion tools like Calibre for maximum Kindle compatibility.
