I have Ubuntu 13.1 installed with the default window manager and DE.
I am trying to enable single click so I can open files and folders with only one click. I tried googling and all results said to open files, then go to preferences from top bar but my top bar has no options.

For 13.10 Go to files then click on Preferences
For 14.04 Go to files, then click on Edit --> Preferences
Click on the Behavior Tab, and then click on Single Click to open items. See image below
sudo apt-get install --reinstall nautilus
