You can delete a file or folder in courses, groups, or personal files. Once a file or folder is deleted, it cannot be recovered.

Note: The Unfiled Folder stores documents, graphics, and any other files from your account that you have posted to different areas of Canvas, such as Discussions. Deleting these items within current courses may create broken links and submissions. 

You can preview a file in a course, group, or personal file storage area.

Students can only delete their announcements within a group. You can delete an announcement on the Announcements page or within an individual announcement.

The Attendance (Roll Call) tool is an external app (LTI) used for taking attendance in Canvas courses. The Attendance tool can be used for online or face-to-face courses. Enabled at the account level, the Roll Call Attendance tool can be used by all courses in the Canvas account.

The Attendance tool always appears as a visible Course Navigation link, but it cannot be viewed by students, so hiding the link in Course Settings is not necessary. If instructors do not want to use the Attendance tool in their courses, no action is required. However, if you do use the Attendance tool, students can view their attendance report through the Roll Call Attendance submission details page.

Note: The Attendance tool must be enabled for your institution before it can be used in Canvas courses. If you are an admin, contact your Customer Success Manager for assistance.

Learning Mastery scores are used by your instructor to measure performance based on classroom standards, or outcomes. Outcome scores may be tied to assignments and other items throughout Canvas.

If your Grades page shows Assignments and Learning Mastery tabs on the Grades page, you can view standards-based scores in the Learning Mastery tab.
