Microsoft PowerPoint Presentation Format (PPT, PPTX)

PPT and PPTX file formats are Microsoft PowerPoint Presentation formats that are supported in the Document/Medical products.

PPT and PPTX files store collections of records and structures that specify slides, shapes, pictures, audio, video, text, and other presentation content. This content can then be shown to an audience as a slide show.

PPT

PPT is the proprietary, Microsoft PowerPoint Presentation binary file format used as the default presentation format for Microsoft Office 97-2003. Files are loaded and saved as raster image files.

The default file extension is .PPT.

PPTX

PPTX is a zipped, XML-based file format that is part of the Microsoft Office Open XML (also known as OOXML or OpenXML) specification, introduced as part of Microsoft Office 2007 and later. PPTX is the default presentation file format for new presentations. Support for loading and saving PPT files is also included.

This file format does not support QFactor, progressive loading, stamps, lossless JPEG compression, or sub-formats.

The default extension is .PPTX.
