Hello @msmith40 
Welcome to the Canvas Community. Thanks for posting your question. So that Community members can better assist you with your question, are you an instructor or a student? If you are an instrutor, are you trying to upload a PPT file into a page of content so that your students can view it? If you are a student, are you trying to attach a PPT file to a discussion topic? Or, are you trying to attach the PPT to an assignment submission? Any details from you would be helpful, Thomas. Looking forward to hearing back from you soon.
