I made a bunch of powerpoints in Google docs. Then I downloaded them to my desktop as MS ppt files. But none of these will upload to my content library. They all fail to upload. I have already checked to ensure that they are not read-only. They are not password protected. I can't think of what else might be the problem.
I have seen this page but it is outdated information and was useless: https://help.wiziq.com/support/solutions/articles/118224-i-tried-to-upload-a-powerpoint-presentation-but-it-failed-why-
I would like to inform you that there is an option now available to upload the files from your Google drive. Please refer to the screen shot attached.
