About formats

PPT is the binary file format of Microsoft PowerPoint, the presentation software first released on April 20, 1987 for the Apple Macintosh and later ported to Windows. The PPT format stores presentations as OLE2 compound documents — a structured binary container developed by Microsoft that organizes slides, text content, images, charts, animations, transitions, speaker notes, and embedded objects across multiple internal streams. Each slide is composed of shape records describing text boxes, auto-shapes, images, tables, and other elements with associated formatting properties including fonts, colors, positioning, and animation sequences. The format evolved substantially through multiple PowerPoint versions, with the PowerPoint 97 release establishing the compound document structure that remained standard through PowerPoint 2003. One advantage is universal recognition — PPT files are understood by virtually every presentation application across all platforms, from Microsoft Office to LibreOffice Impress, Google Slides, and Apple Keynote, making it one of the most portable document formats ever created. The format's mature feature set is another strength: PPT files support complex slide masters, custom animations with timing sequences, embedded multimedia, OLE-linked objects, and VBA macros for automation. Although Microsoft introduced the XML-based PPTX format with Office 2007, the binary PPT format remains widely encountered in archived presentations, corporate document repositories, and organizations that maintain compatibility with older PowerPoint versions.

TCR (Text Compression for Reader) is a compressed plain-text ebook format developed by Barry Childress in the early 1990s for the Psion Series 3 family of palmtop computers. The format was created for Childress's Reader3 application, a text file viewer that needed to fit large books into the Psion's extremely limited storage — typically 128 KB to 2 MB of available memory. TCR uses a dictionary-based compression scheme derived from the earlier ZVR format by Ian Giddings, replacing repeated byte sequences with single-byte tokens that reference a header dictionary. This straightforward approach achieves compression ratios of roughly 40-60% on typical English prose while requiring minimal CPU resources for decompression. The Psion Series 3 ran on a 3.84 MHz NEC V30 processor with no floating-point unit, so TCR's low computational overhead was essential for smooth page-by-page reading. A key advantage is remarkable storage efficiency for its simplicity — users could carry dozens of novels on removable SSD cards that held only a few hundred kilobytes. The format found a dedicated user community among Psion enthusiasts who built libraries of compressed literature for portable reading years before smartphones existed. Though the Psion platform faded from the market in the early 2000s, TCR files can still be opened and converted by modern ebook tools, and the format stands as an early example of purpose-built mobile reading technology from the pre-smartphone era.
