The are two options in Joomla to clear cache files from the cache folders if enabled under the Site Global Configuration settings.

Joomla Global Check-in
Allows Administrators to “check-in” or unlock items currently “locked” whether they are in-use by other users or the item wasn’t closed properly.
Selecting this menu option allows Joomla! administrators to perform a global check-in of all currently pending or locked items. It then shows the results of the Global Check-in. This is useful, for example, if an Article is locked by a User who opened it for editing and never finished the editing session. In this case, other Users are not able to edit this Article. Performing a Global Check-in releases all such items.
