While there are a lot of wonderful things to say about Storyline, there are some behaviours that are not only frustrating but can result in broken courses if you aren't careful.
This tutorial will show you how to package up external files with your Storyline source file so that you can be confident that your course will work as intended.
There are a few situations where this approach really comes in handy, including:
When your course requires additional files to work properly (e.g. if you've added a printable workbook) If you are linking to files that are stored on your local hard drive If it is likely that other developers will need to update the course in the future from a different computer to the one those files are stored on.
