Dear Madison Tokar-Wolff,
Thanks for using Microsoft products and posting in the community.
I understand that you are currently attempting to complete the Microsoft 365 PowerPoint certification preparation materials but are missing four required data files. You can contact the organization or platform that provides the Microsoft 365 certification preparation materials and ask if they can provide these missing documents.
Alternatively, you can currently go to Microsoft Learn where there is a community dedicated to the education section, this is the link to the forum: Training, Certification, and Program Support. You can click on “Ask a question”, there are experts in this field and they will be able to provide you with the information you need.
Thank you for your support and understanding and please feel free to let me know if you have any further updates, thanks.
Best Regards,
Kiki.Z - MSFT | Microsoft Community Support Specialist
