ATutor has a file system used for storing course resource files, and it is managed with the File Manager. The File Manager allows instructors to include files associated with course content into content pages. The File Manager also allows you to create, edit, move, and delete files.
The File Manager can be found in the Manage area, linked from the Content Editor so it can be opened while authoring content pages, or linked throughout the Test Question authoring screens so files can be managed while assembling tests.
