Richard,

What's the proper path for Ron's Brushes in Photoshop?

But the most pressing matter at the moment as far as the other downloaded content goes, it was there to begin with, such as the Barefoot Dancer Tutorial girl, various IRay lights, Genesis clothes & props, but after I browsed around the GUI and tried out different workspaces & styles, when I went back to try the Barefoot Dancer girl in that 4.8 intro tutorial, I noticed that 300+ products which had been downloaded & originally had thumbnails in the Smart Content tab were no longer there, and that only 21 items/products had thumbnails, but even for them, I got an error message saying that this or that could not be found when I double-clicked any of them. I didn't delete anything! All I did was click around the various panes & viewports, and yeah, tried different workspaces & styles like Dark Side, Main Street, Hollywood Boulevard, etc to decide which layout I could see better with. But where did all the content go? Did simply clicking around & adjusting viewport sliders corrupt or delete files? I don't see how that could happen.
