. PPT format (file)
is a document generated by Power point in the MS Office 2003 release.
PPT (slide) is the power point abbreviation. Power is one of the key components of Microsoft's Office software series (and Excel,word, among others). Microsoft Office PowerPoint is a presentation graphics program, and Power Point is a powerful presentation production software. can help you create timeless visuals on your own or online. It enhances multimedia support, uses the documents produced by Power Point to play in different ways, or prints the presentation as a page-by-page slide, playing with a slide machine or a projector, and saves your presentation to a CD for distribution. And you can play the audio stream or video stream during a slide show. Improvements to the user interface and enhanced support for smart tags make it easier to view and create high-quality presentations.
. PPTX Format (file)
A file in the. pptx format is a file generated by power point in versions above Office 2007.
The following versions of Office 2007 do not open files of this format. If you want to open the file in this format, the easiest way is to download a PPT viewer software that can be opened directly after installation. Make a few notes: PPTX is the default format for Microsoft Office PowerPoint 2007 and Microsoft Office PowerPoint 2010, with Microsoft Office PowerPoint Version 2007 is available and can be opened with Microsoft Office PowerPoint 2003 to install a Compatibility pack. Of course it may be easy to install a compatible package, but I haven't tried it. I suggest you install the PPT Viewer, the software is not very large and easy to operate.
