Help me figure out which file is updated, thanks

So under the Design Tab, I have a section called “Site Layout” and I can update the main home page directly and well I was wondering which file is actually updated when I save what I have changed. If screen shot is needed just let me know.

Again thanks.

nevermind figure out another way to go about fixing my problem but still would be nice to have this answered but as of right now Im not in a hurry :slight_smile:

Stored in the database, not in a file.
