No, I am not hovering on a file, but instead clicking on it to give its location in the browser's URL window. What's great about it is that it does work well and allows you to create full HTML sites along with JS and CSS. However, Sharing to Commons and Duplicating the course from this method gives the Access Denied.
I agree with the Absolute issue mentioned and did take your suggestion by making relative links like the ones below, which works just for this course.
However, I still get Access denied when I send it out to Commons or Share the page to a colleague. But thank you for that good suggestion.
I guess what I really need are certified instructions for linking to an item in Files (such as an HTML file). Hasn't anyone done this in Canvas before?
The only other method I know that will actually work without problems is to make my Webpages in Scorm file using Storyline, or Active Presenter, but their dimensions will be locked. The SCORM object works and redirects properly regardless of Sharing Mode. It's just overkill though for a simple set of HTML pages that work together in the files area.
UPDATE: This seems like a similar issue when i-framing HTML. Not quite the same but very similar I suspect
