tpl_modules_create_account.php - cannot find where I saved it to but changes show

When I began editing the file for the registration screen, I changed one of the files to have the text as follows:

Login Details Email Address: *
Support Forum Username: *
Password: * (at least 5 characters)
Confirm Password: *

(Instead of saying "Nick," It says "Support Forum Username.")

I know I edited the tpl_modules_create-account.php.

I cannot find where I uploaded it to as I want to change it again.

I looked in the following directory files:

shop/includes/templates/CUSTOM/templates/
shop/includes/templates/template_default/templates/

both of those contains the file, but not with the new changes, so somewhere I have that file uploaded in a different directory and I cannot find it :(

The site is: http://www.crochetgarden.com/shop in case that is needed.

Thank you DrByte :) I have used that numerous times, but for some reason, these files aren't showing. Is there any way to have the developer tool kit search more than just those areas? I cannot seem to get it to search through the includes/templates folders. Unless maybe I am doing something wrong?

Through much searching, I now have it where it is not require to add in the support forum username, and also was able to omit the field. I should have installed the cart not tying it into phpBB because it causes problems for already existing members, then they have to make a new name etc. So I did find a work- around at least, though still did not figure out what was overriding both the default and custom folder where i thought the only 2 places (I swear, sometimes my computer is possessed).
