The ending PPT denotes an editable slideshow (presentation) of the presentation PowerPoint PowerPoint by Microsoft. The file extension was used from versions 97 to 2003. As of 2007, the default version is pptx for the new format.
A PPT file can contain not only formatted text, lists, images, videos but also music and Excel spreadsheets, which are divided into boards, slides or slides. In addition, many elements can be animated or fade in and out, as well as with different effects. PPT files can also contain macros. These macros may contain malicious code, so you should run a virus scan before running them and always install the latest security updates for Microsoft Office.
PPT files contain a proprietary BIFF (Binary File Format) format, which can be read and stored by numerous programs.
