After you create content and link to files stored in Course Files, you can verify that links are still valid with the link checker tool. For example, if you delete a linked file from Course Files and run the tool, you are informed of a broken link.
You can run this tool on a regular basis to check the validity of your links in your course content. After you copy, restore, or import a course, you can run the tool to be sure everything is linked as you expect. Users with access to items in Course Files can move and delete items, or edit the permissions on an item. These actions may impact the validity of links items in your course.
When you link to a file in Course Files, all course users are given read permission to the file. When you check links, the only permission that is verified is read permission for all course users.
The link checker tool detects broken links for the following areas:
Links to Course Files items in tests (including surveys and question pools) are not checked by the tool.
For each of your courses, you can enable or disable the link checker tool.
Your school can disable this tool for the entire system.
