# 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.

## OpenDocument file format names

LibreOffice uses the following file formats:

ஆவண வடிவூட்டல் | கோப்பு நீட்சி
ODF உரை | *.odt
ODF உரை வார்ப்புரு | *.ott
ODF Master Document | *.ods
HTML ஆவணம் | *.html
HTML Document Template | *.oth
ODF விரிதாள் | *.ods
ODF Spreadsheet Template | *.ott
ODF சித்திரம் | *.odg
ODF Drawing Template | *.ott
ODF Presentation | *.odp
ODF வழங்கல் வார்ப்புரு | *.otp
ODF சூத்திரம் | *.ods
ODF Database | *.ods
LibreOffice நீட்சி | *.oxt

The HTML format is not an OpenDocument format.

ODF Chart is the name of the file format for stand alone charts. This format with the extension *.odc is currently not in use.

## Evolution of the OpenDocument format

The OpenDocument format evolves over time.

ODF பதிப்பு | Date of standard approval by OASIS | First supporting version of the software
ODF 1.0 | 2005-05-01 | OpenOffice.org 1.1.5 or StarOffice 7
ODF 1.1 | 2007-02-02 | OpenOffice.org 2.2 or StarOffice 8 Update 4
ODF 1.2 | 2011-09-30 | OpenOffice.org 3, StarOffice 9, Oracle Open Office
ODF 1.2 (Extended) | - | OpenOffice.org 3.2 or StarOffice 9.2

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

If you want to exchange documents with users that still use OpenOffice.org 1 or StarOffice 7, save the document using the respectively named filter in the File type listbox.

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.

## XML கோப்பு கட்டமைப்பு

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.
