When I change the icons of my folders, where does Ubuntu store these icon settings? I would like to know because I set the wrong picture to be the icon of folder, so I replaced it with another picture which was as the same filename as the wrong one, but the icon didn't change. How can I change the icon?
The iconpacks are stored in /usr/share/icons/ . Many icon packs are stored in this folder. To change the icon for a particular app or folder replace the file with the same name in the icon pack you are using. By default , ubuntu uses unity-mono-dark iconthemes stored at location /usr/share/icons/ubuntu-mono-dark. To change the icon theme, I use unity tweak tool.
