If you are going to be reusing the files contained in your Folder in your LEO unit (for example a PDF) rather than uploading the same content multiple times, you may like to think about only uploading the Folder once, and linking to it from wherever you would like your students to access it from.
To learn more about adding links to your LEO unit, please read our LEO Guide 'URL'
If you are interested in the Folder resource, you may also be interested in learning more about the Book resource. The Book resource is a series of sequential pages (or chapters) which can be used to display dynamic content.
Alternatively, if you are interested in creating a dynamic series of pages which are non-sequential, with the added capability of embedded Quiz questions, you may like to lean more about the Lesson activity.
A Page resource is a dynamic webpage, where you can add text, images, embed video content from YouTube, Vimeo and Kaltura. It also allows to attached files within the page where you can build a context around your content.
