@ 2-ton: The pdf file in that Creative suite is the instructions for downloading and installing. It also tells that the zip is tutorials and something else I forget now.
I downloaded it not sure if I really needed it, since I down loaded Photoshop, Elements, acrobat 7, Indesign, and Illustrator separately too. I have been just trying to learn what each contains and is useful for at this point. I downloaded the smaller files first since my internet is supper slow and sometimes I get cut off.
I hope this helps you out a little in deciding what you want to download.
