File Types That Can be Opened in PowerPoint 365 for Mac

We already learned about the file types that PowerPoint 365 for Mac can save to. But when you go and look at the file types that PowerPoint can open, you'll find that there's no drop-down list in the Open dialog box, as shown in Figure 1, below. All files within any navigated folder are shown, and the only way you understand that a particular file type can be opened is because those files are not greyed out.

Have you ever wondered what all those file types that are not greyed out are? Should you even be concerned about them at all? These are the file types that PowerPoint 365 for Mac can open.

PPTX (PowerPoint Presentation)

This file type is the default open option in PowerPoint 2008 for Mac and later. It is based on XML and can be distinctly identified as different from the older file formats for PowerPoint because it has four letters rather than three, for example, PPTX rather than the older PPT format.

PPT (PowerPoint 97–2003 Presentation)

This file type was the default format for presentations created in PowerPoint versions 2003 and earlier. Most of the time, this is known as the PowerPoint 97 to 2003 format (or the PowerPoint 97 to 2004 format if you include Mac versions of PowerPoint).

PPTM (PowerPoint Macro-Enabled Presentation)

This is identical to the PPTX file format other than the fact that file type creates presentations with macros enabled.

PPSX (PowerPoint Show)

This file type comprises presentations that have been saved as a slide show. In all respects, this is the same as a PPTX file, but when double-clicked, it opens in Slide Show view rather than Normal view. If you use the Open dialog, it opens in Normal view. See our PPT vs. PPS (or PPTX vs. PPSX) article to understand the differences better.

PPS (PowerPoint 97–2003 Show)

This file type comprises presentations that have been saved as a slide show in PowerPoint 97 to 2003. In all respects, this is the same as a PPT file, but when double-clicked, it opens in Slide Show view rather than Normal view. If you use the Open dialog, it opens in Normal view. See our PPT vs. PPS (or PPTX vs. PPSX) article to understand the differences better.

PPSM (PowerPoint Macro-Enabled Show)

This file type comprises presentations that have been saved as a slide show with macros enabled and works in the same way as PPSX files.

POTX (PowerPoint Template)

This file type is a template that you can use as a starter for future presentations. This file format works with PowerPoint 2007 and subsequent versions of PowerPoint.

POT (PowerPoint 97–2003 Template)

This file type is a template in PowerPoint 97 to 2003. You can still open and use these in newer versions of PowerPoint.

THMX (Office Theme)

This file type opens a new presentation based on the Theme chosen, which includes colors, fonts, and effects. Such Office Theme files can also be used within Word, Excel, and other Office applications to impart a standard look to all your documents.

PPAM (PowerPoint Add-In)

This file type opens presentations as an add-in that includes custom commands or VBA code. Typically used in PowerPoint 2008 or later versions.

PPA (PowerPoint 97–2003 Add-In)

This file type opens the presentations as an add-in that you can open in PowerPoint 97 to 2003. Typically used in PowerPoint 2004 or earlier versions.

RTF (Outline/Rich Text Format)

This file type opens the presentation as an outline in Rich Text Format, which you can open in Microsoft Word. This only includes text that is contained within the text placeholders as opposed to text boxes.
