Files are an organisational feature in your topic. You may want to store key files in the section 0 module so that students can navigate to/access them quickly.
The file tool enables a teacher to provide a file (e.g. PDF, image) as a topic resource. Where possible, the file will be displayed within the topic interface, otherwise students will be prompted to download it. The file may include supporting files, for example an HTML file may have embedded images or Flash objects.
Note that students needs to have the appropriate software on their computers in order to open the file.
A file may be used:
to share presentations given in class
to include a mini website as a topic resource
to provide draft files of certain software programs (eg Photoshop .psd) so students can edit and submit them for assessment.
