Template Override

Hey guys,

I tried many different things but I just cannot find out what is the proper directory structure I need to create in my template in order to override a folder.

The file I need to override is:
root/components/com_easydiscuss/themes/simplistic/emails

I tried the following locations but none of them seem to be correct:

root/templates/my_template/html/com_easydiscuss/themes/simplistic/emails
root/templates/my_template/html/com_easydiscuss/themes/emails
root/templates/my_template/html/com_easydiscuss/emails
root/templates/my_template/html/com_easydiscuss/simplistic/emails

Please tell us why my override is not working....
Thank you in advance!
