I have a Vista Ultimate on my system. I want to defrag some specific
directories/files, so I have downloaded "Contig" (sysinternals toolset)
from the Microsoft site. When I try to run this tool as normal user I
got "Access Denied" message. I have logged in as the System
Administrator and got the same "Access Denied" message.

How can I run the "Contig" tool on Vista? What are the proper settings?

Thank you in advance.
