Premiere Pro classroom in a book directions to Path chapter 1

Hi, in the book Adobe Premiere Pro CC 2019 Release, on page 12, I follow the steps to 1. Click Open Project and then 2. In the file navigation dialog box that appears, navigate to the Lesson 01 folder in the Lessons folder; then double click the Lesson 01.prproj project file to open the first lesson.

After opening the project file, I am prompted with a dialog box asking where the media file is. It shows a list of missing items, with the first already highlighted, which is /Volumes/Macintosh HD/MEDIA/Lessons/Assets/Video and Audio Files/Color Work/00020.mp4

I select Locarte, at the bottom right, so that I can locate the file from the files that I downloaded from http://www.peachpit.com/promotions/book-registration-adobe-premiere-pro-cc-classroom-in-141974

At the top of the Locate File dialog box I see the Last Path and the Path. Page 12 of the book says “Using the folders on the left, navigate to the Lessons/Assets folder, and click Search at the bottom right.

However, I do not see any Lessons/Assets folder. Therefore, I am unable to find the correct Path so that I can continue with the steps outlined in the book.

Please advise on how I can locate the correct Path for these files which were downloaded from the Peachpit website.
