The SDD file format is a legacy presentation document type originally developed by StarDivision for the StarImpress module of the StarOffice suite. It was primarily utilized for creating and displaying multimedia slideshows, including text, graphics, and transitions, before being succeeded by the OpenDocument Presentation standard. As an older binary format based on the Microsoft Compound File Binary Format, it lacks modern encryption features and may require legacy software or specialized conversion tools for contemporary access.
