Does “Flush Magento Cache” refresh all caches?

Question

On the Cache Management page in Magento admin, does clicking the "Flush Magento Cache" button do the same thing as selecting all the check-boxes in the grid, choosing the Refresh action and clicking Submit?

Answer 1

Yes it is same as refreshing individual ones.

But sometimes you need to flush the entire cache storage or remove the var/cache directory to ensure all the cache is cleared if custom extensions are installed.
