You can create a link to a file from your lesson by using the Insert/Hyperlink feature in SoftChalk.
STEPS
When you save your lesson, SoftChalk automatically places a copy of the linked file into your lesson folder. That way, when you are ready to move your lesson folder to another computer or package your lesson, all the files are in one folder.
For details on file types you can link to, see the FAQ What types of files can I hyperlink to in my lesson?
You can create links to files or Websites in the text of your Textpoppers, Sidebars, and QuizPopper questions as well as in your main content window.
