Ahh, thanks Glenn. I didn't realise this programme could do what it did without actually deleting stuff. If it's making extra space.... where does it go? No, don't answer that, it will only confuse me.
I don't really understand what the point is of cleaning like it does but not deleting it..? Other than to recover which may happen occasionally but most of us don't clean stuff we want to keep, what benefit is there of it not being deleted??
