KDE4 Icon themes help

[d0b33]

KDE4 comes with the Oxygen icon set which is good but I like Everaldos Crystal project set and have downloaded the one available in the repos but when I apply the icon set it only changes a few icons the rest are the same.

So I decided to keep the oxygen set and changes icons manually...

How do I change the Launcher Menu Icon, Trash Icon, and folder icons?

I've managed to change the rest myself.

thanks
