About formats

PPS (PowerPoint Slideshow) is a binary presentation format from Microsoft that functions identically to PPT with one behavioral difference: double-clicking a PPS file launches it directly in slideshow (full-screen) mode rather than opening the editing interface. The format uses the same OLE2 compound document structure as PPT, storing slides, text, images, animations, transitions, speaker notes, and embedded objects in binary streams. PPS files are typically produced by saving a finished PPT presentation in slideshow format, signaling that the content is intended for viewing rather than editing — though the file can still be opened for editing through PowerPoint's File menu. The format gained widespread use in corporate environments for distributing ready-to-present slide decks, training materials, kiosk displays, and self-running presentations. One advantage is presentation-ready behavior — recipients can launch a PPS file and immediately begin presenting without navigating editing tools, reducing the chance of accidentally modifying content or revealing speaker notes. The auto-play capability is another strength for unattended scenarios: combined with automatic timing and looping features, PPS files power information kiosks, digital signage, and lobby displays that run continuously without operator interaction. While the newer PPSX format has superseded PPS for current workflows, the binary slideshow format remains encountered in archived corporate materials and legacy presentation libraries.

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.
