What is a PPT file?
A PPT file is an editable slide show created by Microsoft PowerPoint or another presentation program, such as OpenOffice Impress or Apple Keynote. It may include formatted text, bullet points, images, movies, sound effects, and music. PPT files are commonly built from one of many templates included with the PowerPoint software, but may also be created from scratch.
PPT files are used for creating presentations in the home and business environments. The PPT file was introduced in 1987 with the release of PowerPoint. It was saved in a binary file format and was the primary file type used to save PowerPoint presentations until it was replaced in PowerPoint 2007 with the .PPTX file extension, which is saved in the OpenXML format. Although the PPT file was replaced by the PPTX file it is still supported by PowerPoint.
You most likely will see the PPTX file more often than the PPT file. However, some users with older versions of PowerPoint may still save their presentations as PPT files. You may receive them via email, USB device, or cloud storage download. You can use PowerPoint to open the file or choose from a variety of other programs, including the free PowerPoint Viewer and OpenOffice options.
Presentation1.ppt - The default filename Microsoft PowerPoint gives to new presentations prior to PowerPoint 2007, which now uses Presentation1.pptx.
