Where is "Clean up" option in folder view menu Yosemite?

I just got a new Macbook Pro Retina with Yosemite. I used Setup assistant from my old one with Mountain Lion - everything went perfectly. But I liked sorting folders containing images using "Clean up by date created" and that option is greyed out in Yosemite in the View menu. Why, and can I restore it?

Thanks,

Richard

Go down in that menu a little bit and use Arrange by... Date created

I hate Arrange by Date, because I have to sort out whether to show all, or less, or previous 7 days,or previous 30 days. Clean Up was much easier to use.
