There are two lesson folders supplied with the book. The DPSIntro folder is for InDesign Creative Cloud (CC) users, and the DPSIntro_preCC folder is for InDesign CS5/CS5.5/CS6 users. Unfortunately, I don’t have every version of InDesign anymore, so I saved the files for CS5/CS5.5/CS6 as IDML files for backward compatibility. For those using the DPSIntro_preCC folder, before you jump into the book, open all of the supplied InDesign files and save them in the same locations as you found them, naming them the same name as the original IDML file. This is necessary because when you open an IDML in InDesign, it opens as an unnamed document and needs to be saved.
