Clean Temp Directory

Joomla has a temporary directory where Joomla itself and third party extensions can store files needed only for a short period of time, typically for the lifetime of a request. Normally, these files are deleted automatically when they are no longer needed. Sometimes, however, a number of server, network or programming issues may result in the premature termination of the page working on this data, leaving unneeded files behind cluttering your site's disk. For example, if an extension installation fails with a timeout or a PHP fatal error the extracted files of that extension may be left behind.
