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.

What is an OEB file?
The Open eBook (OEB) format, formally defined by the Open eBook Publication Structure (OEBPS) specification, is a legacy XML-based standard developed by the Open eBook Forum (now IDPF) in 1999. It acts as a manifest file (typically with an .opf extension) that references a package of HTML or XHTML content, CSS stylesheets, and Dublin Core metadata. As the immediate predecessor to the modern EPUB standard, OEB established the structural protocols for separating content from presentation in digital publishing.
How to open an OEB file
OEB files are not natively executable on standard operating systems. To view the content properly assembled, users must utilize dedicated eBook software such as Calibre, which parses the OEBPS manifest to display the book. While the underlying XML and HTML components can be viewed in standard text editors like Notepad++ or Visual Studio Code, this does not render the formatted eBook experience.
