Arc Media does not operate like the normal file system.
I have lots of media files stored in Arc Media that have links in a Canvas shell.
when running a new version of a course, I want to update the videos, but if I upload a new video with the same name it does not replace it. Instead, I end up with files with duplicate names. This makes it very difficult to upgrade course content.
I end up having to delete the old version, upload a new one, find where it is linked from and update any links to the video.
I tried Canvas support, but they suggested I put it up as a new feature request.
