About formats

LRF is the file format associated with Sony's BBeB (Broadband eBook) specification, jointly developed by Sony and Canon and introduced in 2004 with the Sony Librie EBR-1000EP — the world's first commercial E Ink e-reader. The format supports both reflowable text and fixed-layout page rendering, embedding fonts, images, vector graphics, and metadata within a compact binary container. LRF files use a block-based internal structure with object trees describing page layouts, text streams, image resources, and table of contents navigation. Sony's Reader devices and the companion desktop software (Sony Reader Library) served as the primary ecosystem for LRF content throughout the mid-2000s. A key advantage was its early adoption of high-quality font embedding and text rendering optimized specifically for E Ink displays, delivering a reading experience noticeably superior to many competing formats of the era. The format also supported bookmark synchronization, dictionary lookups, and annotations within the Sony Reader ecosystem. However, Sony officially discontinued BBeB/LRF support in 2010, migrating its Reader platform to the industry-standard EPUB format. Today LRF files are primarily encountered in personal ebook collections from that period and can be converted to modern formats using tools like Calibre. The format remains a historically significant milestone as the native format of the device category that launched the modern e-reader revolution.

PPTM is a macro-enabled presentation format for Microsoft PowerPoint, introduced with Office 2007 as part of the Office Open XML family. Structurally identical to PPTX — a ZIP archive containing XML parts for slides, layouts, themes, and media — PPTM adds the ability to store and execute VBA (Visual Basic for Applications) macro code within the presentation. The deliberate separation of macro-enabled (.pptm) and macro-free (.pptx) extensions was a security design decision: users and administrators can identify macro-containing files by extension alone, and security policies can block or warn about macro-enabled formats while freely allowing standard PPTX files. PPTM files store VBA projects in a dedicated binary stream (vbaProject.bin) within the ZIP package, alongside the same XML slide content used by PPTX. Macros in PowerPoint presentations power automated slide generation, custom ribbon interfaces, interactive quizzes, data-driven content updates, and integration with external data sources. One advantage is workflow automation — PPTM enables repeatable processes like generating monthly report decks from database queries or updating financial charts across dozens of slides with a single button click. The format preserves full compatibility with the OOXML specification, meaning all standard PowerPoint features — transitions, animations, embedded media, SmartArt — work identically to PPTX. PPTM is supported by Microsoft PowerPoint on Windows and macOS, with macro execution limited to the desktop application.
