odp

Two ODP files: a 1 slide presentation of 9.4 KB and a 5 slide presentation of 9.8 KB. ODP is the OpenDocument format used by LibreOffice Impress and by many governments and open-source projects. Like PPTX it is a zip of XML, but with a different internal layout, so PowerPoint-only tools often cannot read it. Use these files to check that your site accepts .odp, that slide counts and thumbnails come out right, and that conversion to PDF works. Having both a single slide and five slides helps you test paging and previews.
