My websites are hosted by BlueHost (shared hosting).
I've recently noticed that my root folder is flooded by thousands to wp-cron.php.* empty files (where * is a number starting from 1 to some thousands).
I suppose these files are generated by the wp-cron.php file and therefore by Wordpress.
How can I avoid generating them? Even though my hosting has unlimited space, they are useless and quite annoying.
