Which Files to upload?

[eluser]JPrieto[/eluser]
Hello everyone,

I am new to CI but very serious about learning it.
I'm familiar with basic level PHP and bought a book to learn it further.

I am trying to duplicate the BLOG site sample in the CodeIgniter site.

MY QUESTION is this:

Once you create php pages ..... WHICH files do you upload to the server?

the entire "system" directory (with the index.php edited)?

OR ......... ??

Thanks
