Should I have access to all files in my account? I am an Administrator and when I show hidden and protected files, if I look at my username\AppData\Local\Application Data there is a little arrow on the folder and I am denied access to it. Also the History and the Temp Internet Files, as well.
In exploring, I'm finding, with all files shown there are many files that I can't open.
Why is this?
Thanks in advance!
To explain this, the folder that you are trying to access does not actually exist

, it is in fact what is known as a symbolic link, a specialist type of shortcut, that is used for compatibility reasons.
As operating systems evolve it is sometimes found necessary to change the names of system folders. In order to better support backwards compatibility the symbolic link is used to redirect programs written for older OS's to the correct location without the need to re-write the application itself.
the data that was held in the Application Data area is now found in the AppData folder, and I would strongly advise that you do not change permissions on these symbolic links as you can hose the entire system with an unintentional change.
Clicking on the symbolic link once it is opened up, permissions wise, will appear to work as previously but it is a lot easier to simply follow the correct route, and without the possible side effects caused by accidental changes or deletion of the links
A technical explanation of links is available here ....
