Which folders makeup the iso image?

I'm going to give Linux another shot but it's been awhile.  And while it purports to be more user friendly, I can't seem to get off of square zero.  Could someone give me the address of an ftp site that has the latest iso of Mandrake, with good bandwidth, and also tell me EXACTLY which folders go on which cd.  I've found folders that say iso image but don't know if the parent folder is included in the iso or just a storage folder on the ftp.  I can't help but wonder how much faster linux would evolve in popularity if it had a start button. I've been more than ready to jump from Windows but never seem to find a plain simple way to acquire the program.  Thanks.
