What is an FB2 file?
FB2 (FictionBook) is an XML-based e-book format originally developed in Russia by Dmitry Gribov. Unlike ZIP-based containers like EPUB, an FB2 file is a single monolithic XML document where the text is marked up with semantic tags describing the structure (epigraphs, verses, citations) rather than the visual appearance. Binary data, such as cover images or illustrations, are embedded directly within the XML file using Base64 encoding. This structural focus facilitates easy conversion to other formats and precise rendering across different hardware devices.
How to open an FB2 file
Support for FB2 is prevalent in e-reading software but rare in native OS environments. Calibre is the primary tool for opening and converting FB2 files on Windows, macOS, and Linux. For dedicated reading, FBReader and CoolReader are cross-platform applications specifically optimized for parsing the FictionBook XML schema. Android users frequently use Moon+ Reader, while iOS users can utilize TotalReader or KyBook.

What is a DOTM file?
The DOTM format is a Microsoft Word Open XML Macro-Enabled Template introduced with Microsoft Office 2007. Structurally compliant with the ECMA-376 standard, it utilizes ZIP compression to encapsulate XML data structures, separating content, styles, and relationships. Unlike the standard DOTX template, the 'M' designation indicates the explicit authorization to store and execute Visual Basic for Applications (VBA) macros. This distinction is a security feature designed to prevent the accidental execution of malicious scripts in standard templates.
How to open a DOTM file
Microsoft Word (2007 and later) is the primary software for opening and executing macros within DOTM files. On macOS, Microsoft Word for Mac provides equivalent functionality. For non-Microsoft environments, LibreOffice Writer and WPS Office can open DOTM files and render the content, though VBA macro execution compatibility may vary significantly compared to the native Microsoft engine.
