What is an SDA file?

SDA is the legacy presentation file format used by StarOffice Impress and early versions of OpenOffice.org, the predecessor suites to today's LibreOffice Impress. It stores slides, layouts, and embedded media using StarOffice's original binary document model, which was later replaced by the OpenDocument Presentation (ODP) standard. SDA files are now mostly encountered when migrating very old StarOffice archives to modern presentation software.

How to open an SDA file

LibreOffice Impress can open SDA files directly thanks to built-in legacy StarOffice format support, automatically converting the content into its modern editing environment. Apache OpenOffice Impress also retains compatibility with this older format.

What is an ODP file?

The ODP (OpenDocument Presentation) format is a strictly defined XML-based file format for presentations, standardized by OASIS and ratified as ISO/IEC 26300. It utilizes a ZIP-compressed container structure similar to a JAR file, holding separate XML components (content.xml, styles.xml, meta.xml, settings.xml) alongside directories for images and thumbnails. This architecture ensures platform independence and long-term archival accessibility, serving as the default format for LibreOffice Impress and OpenOffice Impress.

How to open an ODP file

The format is natively supported by open-source suites such as LibreOffice, Apache OpenOffice, and Calligra Stage. Microsoft PowerPoint (2007 SP2 and later) provides native read/write support for ODP, though some complex animations or specific OpenDocument features may not render identically to the source. Google Slides also supports ODP import.
