Account Details Em

I am trying to find the email that is automatically generated when a new customer fills out the registration form. The customer receives an email "account details for NAME at url".

I would like to find this in my File Manager and edit it.

Where would I find it and what is it called?

Hi,
The solution will probably be to edit the code of the file : "media\com_hikashop\mail\user_account.html.php"
