C:\ProgramData\Application Data is not accessible

This is driving me nuts. On my Exchange server I'm having space issues. Using diruse I tracked down 41 gigs of space being taken up in the C:\ProgramData\Application Data folder. If I give myself permissions to read/execute on that folder, it just keeps opening up a chain of the same folder over and over again. EX: "C:\ProgramData\Application Data\Application Data\Application Data\Application Data" upon double-clicking within explorer.

How do I gain access and pinpoint where this 41 gigs of space is being taken up. I keep reading about Junction Points but I'm still not able to figure out where the C:\ProgramData\Application Data is pointing to.

Thanks again for your hlep. I'm about to pull my hair out.

The folder keeps pointing back to itself
