CourseLab allows to include almost any file in the Course via special External File Object or using the Documents role in one of the Navigation Object. However, be aware that the opening of files that are not intended to be viewed in the browser (for example, Word or Excel documents) is the subject of the local security policies on your computer (for example, corporate security policies). In most cases, when trying to open these files by clicking the link, the user will be prompted to save the file to disk.
