Thank you very much for the quick response Snuffy.
Yes, I have my system set to show hidden folders. The IP that I listed is the internal IP for the folder - it maps to a NAS drive that I have plugged into my router. To be clear, the problem that I'm having is removing the folder from the pinned list when you right click the Windows Explorer icon in the task bar. When I click the unpin icon next to the entry in the pinned list, it doesn't do anything - I attached a screenshot so you can see what I mean.
I updated my spec sheet to include some addtional detail as requested - let me know if you need me to add any more detail.
