What are Flash cookies and how are they different?

They are stored on your computer in the same way as other cookies, but you can't manage them with your browser in the same way.
If you want to delete or disable Flash cookies you can find out how on the Adobe website. But if you disable these cookies it may affect the features available to you on Flash-based applications like some video.
