The PPT file extension represents a presentation file created by Microsoft PowerPoint. It is a binary file format used to store presentations containing text, images, animations, audio, and video. PPT files are widely used for creating and delivering presentations in various settings, including business meetings, educational lectures, and personal projects. The format allows users to organize information into slides, each of which can be customized with different layouts, designs, and multimedia elements. PPT files are typically opened and edited using Microsoft PowerPoint, but other presentation software, such as OpenOffice Impress and Google Slides, can also handle them. While PPT was the standard format for PowerPoint presentations for many years, it has largely been superseded by the newer PPTX format, which is based on XML and offers improved features and compatibility. However, PPT files are still commonly encountered, especially in older presentations or when compatibility with older software versions is required.
