Hi Chris! What a tricky one. To confirm that the question is correct, I labbed this up on my Windows machine. As you can see - the practice exam question is correct. The DIR command will find subdirectories named FILECHK.* as well. Here are the results of my labbing:
C:>dir C:\MYDOCS\FILECHK.* /S
Volume in drive C has no label.
