About formats

POTM (PowerPoint Template with Macros) is a macro-enabled template format for Microsoft PowerPoint, introduced with Office 2007 as part of the Office Open XML family. POTM combines the template functionality of POTX — providing reusable slide masters, layouts, themes, and design foundations — with the ability to embed VBA (Visual Basic for Applications) macro code that executes in presentations created from the template. The format is a ZIP archive containing the standard XML parts for slide masters, layouts, and themes, plus a vbaProject.bin stream housing the VBA project. This combination enables organizations to distribute not just visual consistency but also functional automation: every presentation created from a POTM template inherits both the design system and the programmatic capabilities built into it. Common use cases include templates that automatically populate slides with data from corporate systems, enforce content approval workflows, insert standardized disclaimer slides, or provide custom ribbon tabs with organization-specific tools. One advantage is embedded workflow automation — a POTM template can include initialization macros that configure the presentation environment, add custom menu options, and connect to external data sources the moment a new presentation is created from it. The distinct .potm extension serves a security purpose as well, enabling administrators to apply differentiated trust policies for macro-containing templates versus standard POTX files. POTM is supported exclusively in Microsoft PowerPoint 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.
