I would like to change the layout/view of:
*user account (create and edit),
*order confirmation (on screen and email)
*cart popup
Where the virtuemart files for there sections are located?
You really can't work that out?
User files are in components/com_virtuemart/views/user/tmpl/
Cart order confim and popup in components/com_virtuemart/views/cart/tmpl/
Emails in components/com_virtuemart/views/invoice/tmpl
