To change the default upload location you will need to edit the wp-config.php file located in the root of the WordPress install.
define( 'UPLOADS', 'wp-content/'.'files' );
If you want the upload path to be outside of the the default wp-content folder, you can do this slightly differently:
define( 'UPLOADS', ''.'files' );
