Windows 7 folders acess

How you doing all. I just got a new PC with windows 7.
Is there anyway to acess all files and folders without setting permisson for every folder individually?
I already checked show hidden files and folders, but they all say acess denied when I try to open them, I learned how to set the permisson to open some files, but do I really have to go thru each file to gain acess.
Thanks in advance for any info.
