About formats

RTF (Rich Text Format) is a document interchange format developed by Microsoft and first published in 1987 with Word 3.0. The format encodes document content and formatting as plain ASCII text using control words (backslash-prefixed commands) and groups (curly-brace-delimited sections) that describe fonts, character formatting, paragraph layout, tables, images, and page setup. Because RTF is fundamentally a text format with no binary components, documents pass cleanly through any text channel — email systems, clipboard operations, and cross-platform transfers — without corruption. Microsoft designed RTF explicitly as a cross-application and cross-platform exchange format, and it achieved broad adoption: virtually every word processor, text editor, and document tool on every operating system has supported RTF reading and writing for decades. One advantage is exceptional cross-platform compatibility — an RTF document created on any application renders with consistent formatting on any other, making it the most reliable format for text exchange between incompatible systems. The text-based structure provides another benefit: RTF files resist corruption, are trivially generated by programs (requiring only string concatenation), and can be debugged by reading the raw markup in a text editor. While RTF lacks modern features like tracked changes and advanced layout controls, and Microsoft declared the specification frozen at version 1.9.1 in 2008, the format persists as a dependable interchange option where DOCX compatibility cannot be assumed.

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.
