Thanks Greysts. But I have concerns about CCleaner after reading a thread about it called Crap Cleaner. But I understand that if I uncheck certain boxes it will be more user friendly for novices. But also I am not too keen on losing all my passwords as I like stuff like that to remain intact. Someone recommended Steve Gould's 'Cleanup!' - would that be better for me??? I have only defragged once in the last year, I guess that hasn't helped the situation.
