About formats

DOTM is a macro-enabled template format for Microsoft Word, introduced with Office 2007 as part of the Office Open XML family. DOTM combines the template functionality of DOTX — providing reusable styles, page layouts, boilerplate content, and formatting definitions — with the ability to embed VBA macro code that executes in documents created from the template. The format is a ZIP archive containing XML parts for styles, document defaults, and theme definitions, plus a vbaProject.bin stream for the VBA project. This combination enables organizations to distribute not just visual consistency but also functional automation: every document created from a DOTM template inherits both the formatting framework and programmatic capabilities. Common use cases include templates that auto-populate document fields from corporate directories, enforce naming conventions, generate tables of contents, insert dynamic headers with project metadata, or validate document structure before submission. One advantage is embedded workflow automation — a DOTM template can include initialization macros that configure the document environment, register custom ribbon commands, and connect to data sources the moment a new document is created from it. The distinct .dotm extension allows administrators to apply differentiated trust policies for macro-containing templates versus standard DOTX files. DOTM is supported exclusively in Microsoft Word desktop editions where VBA execution is available.

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.
