Magento – Magento 2 : Flush static files cache delete the files in pub folder

Before deleting pub/static make a backup of pub/static/.htaccess and restore it again. otherwise your all css and js will show 404 error!

1. Remove pub/static (keep the .htaccess backed up and copy it again)
2. Remove var/cache
3. Remove var/composer_home
4. Remove var/generation
5. Remove var/page_cache
6. Remove var/view_preprocessed
7. Run php bin/magento setup:static-content:deploy

Sometimes the cache location (like "/tmp/") or service (like Memcache) is shared with other applications. "Flush Magento Cache" removes only those entries that Magento reliably tracks as it's own. "Flush Cache Storage" clears everything but might affect other applications if they're using it.

Normally the location is "var/cache/" in Magento's folder so is not shared after all. It is safe to use either button. Sometimes (rarely) entries are not clearly tagged or Magento loses track of them and only the second button has an effect on them. I tend to use the second button when I'm having difficulty tracking down the cause of a problem.
