If you copy or link to another instructor's course and the original course had posted files, including a syllabus, your copied or linked course has links to those files. Any files listed under Course Documents in the original course are listed under Course Documents in your course.
Similarly, any files posted to an assignment in the original course are posted to the assignment in your copied or linked course (if you copied the assignments).
However, your course has links to the original course's posted files: you do not have access to the actual files. If you remove one of the links, you lose the connection to the file. In File Manager, these links are listed in the Copied Files folder.
Also, if the instructor of the original course deletes any of his or her posted files, your course loses the links (because there is no longer a file to link to).
Tip: You can open a linked file and save it to your system.
