Hi,
The simplest is to edit your view files via the menu Display->Views.
The changes will be saved automatically as overrides and that way you won't make any file location mistakes when editing them.
Otherwise you can do it manually in the folder "template/you_template/html/com_hikashop/...", the classical override way in Joomla.
