Where is PowerPoint's equivalent of Word's normal.dotm?

Question

Where PowerPoint stores default presentation file, opened each time program is started, a Word's normal.dotm equivalent (if it exists)?

Or how can I change some elements of file, that is always created, when opening PowerPoint?

Answer 1

In PowerPoint 2016:

1. Set up a blank ppt to your desired specifications (slide size, font, color, theme, etc).
2. Save the ppt as "Blank.potx" in folder "C:\Users\insert-username-here\AppData\Roaming\Microsoft\Templates".

Note: Powerpoint will want to save this in a default template folder once you change the file type to .potx so make sure you set the file type first then change the folder location.

The next time you open Powerpoint the very first template will be "Default Theme" (your personalized default). Next to that will be the original "Blank Presentation" and all the other standard themes.

Where does PowerPoint store default presentation files?

The exact locations and names are different for each version of PowerPoint.

See the link below for more information about each version..

Normally when you start PowerPoint you can create a new blank presentation or start a presentation based on one of the included templates. But what if you want PowerPoint to base all new presentations on your own template?

You can, and it's easy. You just need to open your template or a presentation based on it, save it in the correct location and give it the right name. The exact locations and names are a different for each version of PowerPoint.
