I too agree with karstad33. There should be a check all/uncheck all icon, like different email services have to select/de-select all messages at once. Many softwares also have this. It will definitely make CCleaner more intuitive and easy to use. I just got to know that by clicking IE/FF icon etc, one can get the same result, only after reading this topic thread. This sounds stupid but I have been using CCleaner for over 3 years and never came across this feature till just now!
