  11. Observe the download status of the articles, and return to the library view after they have all completed.

Solution 4: Minimize your folio content

You can use many methods to minimize folio content. One of the most obvious is to remove embedded videos and have them served through web content overlays instead. Any method that helps to reduce the folio down to something below 100 MB is beneficial.
