Conflict with WP DB Driver

Hi,

I have been attempting to use the WP DB Driver plugin which is the only solution I have been able to find to enable WordPress to run on php 5.5 due to deprecation of MySql.

This plugin creates a file named db.php in the wp-content folder, as does W3 Total Cache. If database caching is enabled in W3TC, it overwrites this file but even when database caching is disabled, it appears to remove any db.php file that is present in the wp-content folder. Is there any way to prevent this from happening?
