you may want to apply ONE (OldNewExplorer) to get the best windows explorer back instead of that godawful ribbon menu.
What do you mean? The folders shown in Computer or the list on Quick Access?Why pin folders to favorites?
Simply move the desired folders to your USER directory (Users\[user]) then you can access them directly. I do it via the toolbar at the top left; it's simply a directory listing of my user directory, although I'm not sure if you can create toolbars under Win10.
