For the "Developing Zynq Hardware With Xilinx Vivado Design Suite" Technical Training Course, the ZynqDesign folder does in fact start out empty. You will create that design from scratch as part of the course.
Got it. Now I see that the bulk of initial configuration is part of Lab 2. Thanks for following up!
I started on the MiniZed Lab/Training today, but it looks like the hardware files (Vivado Project files) aren't in the ZynqDesign subfolder. Is this an oversight? Were the files intentionally removed from the download zips? The powerpoints are in the Lab_instructions subfolder and the Support_Documents subfolder has lots of stuff in it as well.
