Win 7 Starter - missing folders

On my AAO 532 I am the only user. I am also the administrator.
Yet there are some folders that I cannot access - and I need to,
if only to delete all the temporary files bloated there by various apps.

Specifically these are in this path:

C:\Users\CHRISJ~1\AppData\Local\Temp\ or
C:\Users\ChrisJBrady\AppData\Local\Temp

I have access via Windows Explorer to all the user-folders such as

C:\Users\ChrisJBrady\Downloads
C:\Users\ChrisJBrady\Library
C:\Users\ChrisJBrady\Pictures
etc.

But I cannot get access to

C:\Users\ChrisJBrady\AppData etc.

What setting(s) do I have to configufre to gain access to \AppData
using Windows Explorer?

Many thanks.
