About formats

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.

POTX (PowerPoint Template XML) is the Open XML template format for Microsoft PowerPoint, introduced with Office 2007. A POTX file is a ZIP archive containing XML parts that define slide masters, slide layouts, theme colors, theme fonts, theme effects, placeholder configurations, and default content — everything needed to establish a consistent visual foundation for new presentations. When applied, a POTX template creates a new PPTX document inheriting the template's complete design system, including multiple slide layout variants (title, content, two-column, comparison, blank, and custom layouts) each with precisely positioned placeholders. The XML-based structure brings advantages over the legacy POT format: templates can be inspected and modified using standard XML tools, design elements are cleanly separated into dedicated files (theme.xml, slideMaster.xml, slideLayout.xml), and built-in ZIP compression yields smaller file sizes. One advantage is design system management — POTX files encapsulate an entire visual identity as a distributable package, and the modular XML structure makes it straightforward to update individual elements like color schemes or font stacks without rebuilding the entire template. Broad compatibility is another strength: POTX templates work in PowerPoint on Windows and macOS, LibreOffice Impress, and online platforms. The format integrates with PowerPoint's template gallery and organizational template libraries, enabling centralized design governance across large teams.
