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 OTT file?

An OTT (OpenDocument Text Template) file is a standardized document template defined by the OASIS Open Document Format for Office Applications (ODF) specification (ISO/IEC 26300). Based on XML syntax and encapsulated within a ZIP-compressed container, the format stores styling definitions, page layouts, and manifest files separate from content, allowing users to generate multiple .ODT files with consistent formatting. It supports lossless compression and interoperability across open-source office suites.

How to open an OTT file

Native support is built into ODF-compliant word processors such as LibreOffice Writer and Apache OpenOffice. Microsoft Word opens OTT files via integrated ODF conversion filters. Because the file functions as a template, opening it typically instantiates a new, untitled document (.odt) rather than editing the template file itself, unless specifically opened for editing via the application's file menu.
