A file with .pptx file type is a Microsoft PowerPoint Open XML (PPTX) file created by Microsoft PowerPoint. You can also open this type of file with other presentations, such as OpenOffice Impress, Google Slides or Apple Keynote. They are stored as a compressed ZIP file, which uses a lot of other files with formatted text, images, video clips and more to open them.
What is a PPTX file?
PPTX files are used in Microsoft PowerPoint, a presentation program used to display content in a slide show format. Each image can contain graphics, formatted text, videos, music, animations, and more.

First introduced with Microsoft Office 2007 in Office Open XML Standard, PPTX is the default format when you create a presentation with modern versions of PowerPoint. Microsoft introduced this open format to a large extent due to increased competition from Open Office and its open document format (ODF). The PPTX format replaced the proprietary PPT format that PowerPoint previously used.

How do I open a PPTX file?
Since PPTX files have been standardized, you can open them in many applications on different platforms. Although Windows does not open them, if you do not have a copy of Microsoft Office 2007 or PowerPoint 2007 or later, you can download a third-party open source such as Apache OpenOffice or LibreOffice to open your files.
Mac Users just need to double-click the file to open it in the Apple Keynote application.
If you'd rather save, open and edit all your Office Open XML files in the cloud, you can do it by uploading your document via PowerPoint Online or Google Slides.
Alternatively, if you're a Chrome user, you can download Office Editing for Docs, Sheets, and Slides (an official Google add-on) for your web browser. It allows you to upload a PPTX file directly from your local hard drive to your Google Drive by drag and drop it in any Chrome tab.
