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.

What is a PPSX file?

The PPSX (PowerPoint Open XML Slide Show) format is a presentation file introduced by Microsoft with Office 2007, adhering to the Office Open XML (OOXML) standard (ISO/IEC 29500). It acts as a read-only slideshow version of the PPTX format, launching directly into presentation view rather than the editing interface. Structurally, it is a ZIP archive containing XML documents that define slide layouts, themes, and content, but it explicitly excludes the vbaProject.bin part found in macro-enabled variants, ensuring it cannot execute code.

How to open a PPSX file

Native support for PPSX is built into Microsoft PowerPoint 2007 and newer versions on Windows and macOS. To edit a PPSX file rather than view it, users must open PowerPoint first and select the file via the 'Open' menu. Alternative software includes LibreOffice Impress, Google Slides, and Apple Keynote, all of which can parse the OOXML structure, though some transition animations may not render identically to the Microsoft engine.
