About formats

AW is the document format of Applix Words, the word processor component of the Applix office suite (later renamed Anyware Office) developed by Applix, Inc. for Unix and Linux workstations. The suite targeted enterprise Unix environments during the 1990s, providing word processing, spreadsheet, graphics, and presentation capabilities on platforms like Solaris, HP-UX, AIX, and Linux where Microsoft Office was unavailable. AW files store formatted text documents with support for character and paragraph styling, page layout, tables, headers and footers, and embedded graphics. The format uses a proprietary binary structure optimized for the Applix application's internal document model. Applix Words gained particular visibility in the Linux community during the late 1990s when it was bundled with several commercial Linux distributions as their default word processor before OpenOffice.org became widely available. One advantage was native Unix platform support — Applix provided professional word processing capabilities on Unix workstations at a time when few commercial alternatives existed. The format's tight integration with other Applix suite components enabled cross-referencing between word processing documents, spreadsheets, and presentations. Applix was acquired by Cognos in 2003, and the office suite was discontinued. AW files are primarily encountered today in archived documents from Unix enterprise environments of the 1990s and early 2000s.

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.
