Nautilus does not show the left bar, how do I turn it back on?

When I open nautilus does not open the left bar where it says computer and down markers such as music, documents, videos, downloads. I reinstalled nautilus from the synaptic package manager but nothing happened. What I can do to make that bar visible again?

Solution 1:

Just press F9 when you open nautilus.

Another way to do this is

Click on 'view' then check the 'side pane' option.

Solution 2:

You can activate or deactivate the sidebar simply by pressing F9. You can also go up to the global menu, then select View → Sidebar → Show sidebar.

Solution 3:

Just press F9 or if you like it the 'mouse' way, jut select 'Side Pane' from the 'View' menu.
