I tried to run Nemo under / and nothing came up.
I have my friend's laptop and he died. His son want the documents off his Win10 laptop. When I copy a file from it to my Desktop, that copied file is locked and cannot be viewed, etc.
I'ld be willing to try to change Win10 permissions using chmod/chown as well, but need some guidance to get started.
Thank you, Debian Community.

continuing my own research, I learned to right click open as root
