I cant find theme all file and cant edit

[Arminuks]

Hello,

 

I'm using 1.7.4 version prestashop.

 

I'm uploud new theme and delete old theme (classic), and now I want edit admin login page using this topic 

but when I going to "ADMIN_DIR/themes/default/template/controllers/login/content.tpl" I cant find the controllers file at my new theme location, and problem that I do not have old themes and cant edit old themes (classic), I'm only have new uplaud themes (newThemes). What can I do?

 

Thanks,
