Unable to view exercise files in R Essential Training Linked In learning Course

I am enrolled in Prof Barton Poulson's linked in course, R essential training. I downloaded the related exercise files, and was using them. Then they disappeared from the File pane of the IDE and I cannot find them or recover them.

I tried to reload them, and get them to reappear in the file pane and the contents of each individual file inthe source pane. The download seems to be going successfully but I can't find them or open them.

Any help would be appreciated.

The file pane is just a file explorer, there is nothing unique about it, it will simply show the content of any folder in your computer. Very likely you are just looking at the wrong place.
