I've come across a scenario in which I’m now unable to delete files using the user interface.
Steps to replicate
- Create a file resource within a course
- Add an image to the file resource and save changes
- Within the same course, add a page resource
- Within the page resource, add an image (Browser Repositories > Server files > The image you uploaded previously, click 'Make a copy of the file')
- Save changes to the page
- Within the course, now delete File resource originally uploaded
- Go to the Page resource and check the image still loads
- Try and delete the image uploaded in the server files area using the file picker.
