If you are like me and hate the single click to open a folder or file and want to change it to double click.
Open Dolphin, the file manager.
Next from the menu (Thats the little spanner in the top right hand corner), select Settings > Configure Dolphin.
Click on the Navigation tab, then enable the double-click to open files and folders.
