A PPT file is an editable slide show created with Microsoft PowerPoint often used for presentations or slideshows. It may include formatted text, bullet points, images, movies, sound effects, and music. The file is commonly built from one of many templates included with the PowerPoint software, but may also be created from scratch.
NOTE: PowerPoint 2007 and later saves presentations in the OpenXML format and uses the .PPTX file extension.
Common PPT Filenames:
Presentation1.ppt - The default filename Microsoft PowerPoint gives to new presentations prior to PowerPoint 2007, which now uses Presentation1.pptx.
