Where are the DB settings located? i've been learning Drupal 7 using Acquia DevDesktop and i have several sandbox type website running on my laptop but now i'm trying to access the databases from the command line. but in the settings.php almost the only that's not comment out are at the bottom, where it makes reference to inc.'s like this.

if (isset($_SERVER['DEVDESKTOP_DRUPAL_SETTINGS_DIR']) &amp;&amp;
file_exists($_SERVER['DEVDESKTOP_DRUPAL_SETTINGS_DIR'] .          '/loc_rmywebsite_local.inc')) 
  require($_SERVER['DEVDESKTOP_DRUPAL_SETTINGS_DIR'] .     '/loc_mywebsite_local.inc');


but then when i do a search for these inc files locally on my laptop, nothing comes up, as if they don't exist. so
One, where are these files?
and two, find where the DB settings are for these local sites so i can start learning how use the command line, or maybe Drush. 

yes, i should probably have written down these setting but didn't.
