Auto delete cache files?

Any option to delete every day? Today I found the cache folder more than 400MB whereas the total project size is 40MB.

@sunil951, I would be surprised if it continues growing once your website is stable (in production). Did you monitor it over the course of a few days/weeks after deleting the cache?

I can imagine that updated/new pages add to the size, but that should be it.

What's your rationale? Does disk consumption hurt your site in any way?
