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 DOCM file?
A DOCM file is a macro-enabled document created by Microsoft Word (2007 and later), compliant with the Office Open XML (OOXML) standard (ECMA-376 and ISO/IEC 29500). Structurally, it is a zipped archive containing XML files for content and styles, identical to the DOCX format, but with the specific distinction that it is authorized to execute Visual Basic for Applications (VBA) macros stored within a vbaProject.bin part. This separation ensures security by preventing macro execution in standard DOCX files.
How to open a DOCM file
Opening DOCM files requires software capable of parsing OOXML and executing VBA scripts. Microsoft Word is the standard environment for full functionality. LibreOffice Writer and WPS Office can open DOCM files and display content, but support for executing the embedded proprietary VBA macros may be limited or require code refactoring. Security settings in most software will disable macros by default upon opening to prevent malicious code execution.
