Overriding Craft Commerce config files Is there a way to override the Craft Commerce config files ?

I'm specifically talking about this one, deep inside the plugin craft/plugins/commerce/etc/currencies.php

I'd like to change the default amount of decimals for Euros
For that particular file, the answer is no... not without hacking the core Commerce plugin file, which we don't recommend.

If you think there's a bug in the file, send an email to support@craftcommerce.com.  If you'd like to create a feature request to open up that file so it is configurable, you can do that here.
