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.

What is an ODT file?
ODT is the text document format of the OpenDocument standard (ISO/IEC 26300), maintained by the OASIS consortium. It employs an XML-based architecture where the document's content, styles, settings, and metadata are stored in separate XML files (e.g., content.xml, styles.xml) and compressed into a single ZIP container. It serves as the default native format for the LibreOffice and Apache OpenOffice suites.
How to open an ODT file
The file opens natively in LibreOffice Writer and Apache OpenOffice Writer on Linux, Windows, and macOS. Microsoft Word (2010 and later) and Google Docs also possess built-in import filters to read and edit ODT files, though minor formatting discrepancies may occur during conversion.
