# XML File Formats

By default, LibreOffice loads and saves files in the OpenDocument file format.

The OpenDocument file format (ODF) is a standardized file format used by many software applications. You can find more information at the Wikipedia site: wikipedia.org/wiki/OpenDocument.

The OpenDocument format evolves over time.

In current versions, you can select to save your documents using ODF 1.2 or ODF 1.0/1.1 (for backward compatibility). Choose LibreOffice - Preferences Tools - Options - Load/Save - General and select the ODF format version.

If you want to define another file format as the default, choose LibreOffice - Preferences Tools - Options - Load/Save - General to find alternative file formats for each LibreOffice document type.

## एक्सएमएल फ़ाइल स्ट्रक्चर

Documents in OpenDocument file format are stored as compressed zip archives that contain XML files. To view these XML files, you can open the OpenDocument file with an unzip program. The following files and directories are contained within the OpenDocument files:

1. The text content of the document is located in content.xml.

   By default, content.xml is stored without formatting elements like indentation or line breaks to minimize the time for saving and opening the document. The use of indentations and line breaks can be activated in the Expert configuration by setting the property /org.openoffice.Office.Common/Save/Document PrettyPrinting to true.

2. The file meta.xml contains the meta information of the document, which you can enter under File - Properties.

   If you save a document with a password, meta.xml will not be encrypted.

3. The file settings.xml contains further information about the settings for this document.

4. In styles.xml, you find the styles applied to the document that can be seen in the Styles window.

5. The meta-inf/manifest.xml file describes the structure of the XML file.

Additional files and folders can be contained in the packed file format.
