I tried changing as you said. It didn't work. Here is my path:

C:\Users\Jack\Documents\Word Files

I added another extension:

C:\Users\Jack\Documents\Word Files\BenQ 1080ST

BenQ 1080ST is the first folder of 21 folders. It opened to the first Word document inside of the BenQ 1080ST folder. Clearly it wants to open to the first document. I can erase all of the un-foldered Word documents but that seems like a cheap way to solve the problem.
