Can you explain #1 a bit more? I am not sure what folders you are referencing.

Re: #2 - I know about notepad++ but again I'm not sure what code I'd replace
or what code you even mean.

And #3 is a complete whoosh.

But if there's more involved just trying to copy a simple site like this, it
seems like trying to "copy" even more complex sites would create even more
problems/errors. 

Is there a way to easily copy a website kind of like archive.org as a way to
backup and reference in the future without extensive technical knowledge?
