Right now I'm watching my System monitor's Processes tab and I found out that one of the top CPU usage goes to Nautilus, although Nautilus is not currently opened. It is Nautilus -n when I move mouse over it in System Monitor.
What is that thing and should it be so normally?
nautilus [OPTION...] [URI...]
Browse the file system with the file manager
-h, --help Show help options
--help-all Show all help options
--help-gtk Show GTK+ Options
-c, --check Perform a quick set of self-check tests.
--version Show the version of the program.
-g, --geometry=GEOMETRY Create the initial window with the given geometry.
-n, --no-default-window Only create windows for explicitly specified URIs.
--no-desktop Do not manage the desktop (ignore the preference set in the preferences dialog).
-q, --quit Quit Nautilus.
--display=DISPLAY X display to use
