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.

DOC is the binary document format of Microsoft Word), the word processor first released in October 1983 for MS-DOS and later becoming the dominant document creation tool worldwide. The format stores documents as OLE2 compound document files — a binary container with multiple internal streams holding text content, formatting information, embedded objects, macros, and metadata. The text stream uses a complex system of formatting runs, section descriptors, paragraph and character property tables, and style definitions to represent arbitrarily complex document layouts including columns, headers, footnotes, tables, floating images, tracked changes, and mail merge fields. The format evolved substantially through Word versions, with Word 97 establishing the binary structure that remained standard through Word 2003 and created the .doc files most commonly encountered today. One advantage is near-universal compatibility — DOC files can be opened by virtually every word processor and document viewer across all platforms, from Microsoft Office to LibreOffice, Google Docs, and Apple Pages. The format's rich feature support is another strength: DOC handles complex layouts, embedded OLE objects, VBA macros, and revision tracking that power enterprise document workflows. Although Microsoft introduced the XML-based DOCX format with Office 2007, DOC remains heavily present in existing document archives and continues to be produced by organizations maintaining compatibility with older Word installations.
