How to disable "recent files" folder in Nautilus?

When I turn off " record activity" in the privacy settings, my activities are still recorded in the "recent files" folder (even when I am using a truecrypt volume).

I haven't figured out a PERMANENT solution to this problem. It sucks to delete history via terminal manually and what happens if I forget?

The method with editing ~/.config/gtk-3.0/settings.ini doesn't work with Nautilus 3.8. But there is better and simpler way. Simply open dconf-editor, navigate to org->gnome->desktop->privacy and uncheck the remember-recent-files key. That takes care of it, once for all!

Disable the Nautilus Recent Files list

To permanently disable any recent files from showing up in the Nautilus Recent sidebar item, open the ~/.config/gtk-3.0/settings.ini file with a text editor:

gedit ~/.config/gtk-3.0/settings.ini

and under "[Settings]", add the following lines:

gtk-recent-files-max-age=0
gtk-recent-files-limit=0

If this file does not exist, create it. Make sure the header says "[Settings]" and not "Settings". This is how the file should look after editing it:

[Settings]
gtk-recent-files-max-age=0
gtk-recent-files-limit=0

(there can be other items below these, of course).

To apply the changes, log out and log back in.
