Flex graphic assets: SWF or SWC?

Question

Which is a better format to store graphic assets for a Flex application, SWF or SWC?

Are there any real differences, and if so what are they?

Answer 1

A SWC is simply a SWF and some metadata wrapped into a zip file. Other than the fact that runtime loading of SWC isn't supported, I don't think there are any major differences between using the two formats.
