What is PPTX and PPT?
Presentation created using the MS PowerPoint program create files that have either the PPTX or PPT file extension. Presentations can be saved with either of the two formats that are proprietary to MS PowerPoint. PowerPoint officially launched under its own name in 1990 alongside Windows 3.0.
Before 2007, the PPTX format was rare though it existed at the time and some years before that. Up until 2007, PowerPoint saved to the PPT format by default. With Office 2007, the default format changed to PPTX though users can still select the PPT format for saving a presentation. PPTX, like the DOCX format for MS Word documents, is the Open XML format that Microsoft developed for its suite of productivity apps. Both the PC and Mac versions of the PowerPoint app support creating, viewing, and editing of PPTX and PPT files. For users who have an older version of MS Office installed, opening a PPTX, or any other XML format may require them to install the Microsoft Office Compatibility Pack.
How do I open a PPTX or PPT file online?
Upload the PPTX or PPT file you want to view to Jumpshare and click to watch the slideshow. You can view the slides in two different modes; the regular viewing mode, or the full screen mode. In regular mode, you can jump to any slide using the slide navigation tool, you can jump to the start or end of the presentation, and you can view the slideshow in full screen mode. In full screen mode you can navigate between the slides using the left and right arrow keys.
