What is an FODT file?

The FODT format (Flat XML OpenDocument Text) is a document file type defined by the OASIS OpenDocument Format (ODF) v1.2 specifications (ISO/IEC 26300). Unlike the standard ODT format, which acts as a ZIP-compressed container holding multiple XML sub-files and assets, FODT stores the entire document structure-including text, layout styles, and Base64-encoded images-within a single, uncompressed XML file. This human-readable architecture facilitates version control integration (e.g., Git) and direct XML parsing without requiring decompression libraries.

How to open an FODT file

FODT files are natively supported by the LibreOffice suite and Apache OpenOffice, which serve as the primary reference implementations for the ODF standard. Users on Windows, macOS, or Linux can open these files directly in LibreOffice Writer. Due to the uncompressed XML structure, the files can also be inspected or modified using code editors like Visual Studio Code or Notepad++, though this renders the raw markup rather than the formatted text.

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.
