An ODP file is a presentation format based on the OpenDocument standard, much like Microsoft PowerPoint's PPTX. It stores slides containing text, images, videos, animations, and transition effects. ODP files are structured as compressed ZIP archives with XML documents defining their content and layout. They also preserve metadata, such as author details and editing history. Designed for cross-platform compatibility, ODP works seamlessly with LibreOffice Impress, Apache OpenOffice, and even Microsoft PowerPoint. The OpenDocument format (ODF) is an open, OASIS-standardized format for office documents, ensuring long-term accessibility and interoperability.
