If you remove USER/OneDrive/My Documents folder from windows 10, then execute the above as app starts, app will completely crash. Seems to search for USER/OneDrive/My Documents no matter what even if I move it to USER/My Documents to get it off the cloud. This is supposed to be a "secure" path we can write to files, not sure why this is in the cloud on microsoft to begin with with directory, must be a better app directory it can look for for storing sensitive files.
