Temporary files

The temporary files directory in Drupal is the location on your web server where Drupal core and contributed modules upload files for processing.

Acquia’s require line in your website’s settings.php file configures the location of your temporary files directory to /mnt/tmp/[sitename].[env], where [sitename] is your application name and [env] is the environment. This location is available to you as an environment variable.

For more information about your application name, see the Sitename definition page. For a full list of Acquia Cloud file locations, see File locations.

For more information about Twig caches, see Twig caches.


Do not set the temporary directory to /tmp. The /tmp directory is smaller than /mnt/tmp/[sitename].[env], and may quickly fill up.

Drupal modules that write to temporary directories may require additional configuration to function properly in environments with multiple web servers, such as production environments for Acquia Cloud Enterprise and Acquia Cloud Site Factory.
