You can move your wp-content folder elsewhere if you like or rename it to something else. However, there are a number of constants related to the wp-content and plugins directories. To make sure your plugins continue working correctly, you should define all of these constants in your wp-config.php file. Add the constant definitions anywhere in the configuration file,
define(‘WP_CONTENT_DIR’, $_SERVER['DOCUMENT_ROOT'] . ‘/files’);
define(‘WP_CONTENT_URL’, ‘http://example.com/files’);
define(‘WP_PLUGIN_DIR’, $_SERVER['DOCUMENT_ROOT'] . ‘/files/plugins’);
define(‘WP_PLUGIN_URL’, ‘http://example.com/files/plugins’);
define(‘PLUGINDIR’, $_SERVER['DOCUMENT_ROOT'] . ‘/files/plugins’);
