help unpacking Mac software

Hi
I’ve downloaded Aperture.3.5.1.Multilingual.Mac.App.Store from here.
when i unrarx the .rar files i get a .nfo file, a bunch of zip files (named cr-b2u00.zip) and a file_id.dlz file.
i can’t read the .nfo and .dlz files and when i unzip the other files they have .rar files inside that my mac says are not far files.
any help would be great.
thanks

I had a look at theses files…. There are no Installtion files.
Its all Content only
Select all using winrar Extract here or to anther folder
Open Aperture_v3.5.1.part01
Drag that CORE folder into your folder
Open Aperture_v3.5.1 rar
Drag Aperture.app file out into your folder.
Now U have a Content folder.
add that to to Program files. if any..
