Using alternative app directories

Nextcloud can be set to use a custom app directory in /config/config.php. Customise the following code and add it to your config file:

'apps_paths' =>
      array (
              0 =>
              array (
                      'path' => OC::$SERVERROOT.'/apps',
                      'url' => '/apps',
                      'writable' => true,
              ),
              1 =>
              array (
                      'path' => OC::$SERVERROOT.'/apps2',
                      'url' => '/apps2',
                      'writable' => false,
              ),
      ),

Nextcloud will use the first app directory which it finds in the array with ‘writable’ set to true.
