If you are using List view and have a file list that is longer than the window height, there is no way to right-click and choose 'Create Folder'. If there is no blank space, right clicking always selects a file and gives the file options. This also means that you cannot deselect files once selected (only by selecting a different file).

Other information:
It would be better if the options from right-clicking on blank space were also available from right-clicking on a file (perhaps in a sub menu?). Or perhaps always creating some blank space *somewhere* to be able to click on.
