thanks so much both to you and also thanks for this application but i should say that i agree with mara- about this option.if this is about replacing old updates it is ok, but it must delete only "updates" not clear all content from users folders i think.because most of the people may not be aware of the dangerous sides of this option.and also some of them may not know how to recover their data which are accidentally removed. again i will thank you but i think you will understand me about this situation.
