How to know and find all emails in Magento?

I need to find out where are all ema开发者_Go百科ils templates (newsletter, registration confirmation, etc..) to customize AND and translate them.

Where can I find an exhaustive list?

You can get a pretty good list from System > Transactional Emails > Add New Template > Load default template.

Also just about all emails start out in the folder app/locale/en_US/template/email/
