Missing path information in .qip file with QUARTUS II 9.1

Hi all,

I am designing a system with Nios, I was unable to find the path information in Quartus II v9.1 in the .qip file. I was able to find the path information in Quartus v9.0, can any one help me on the setting to get back the path information?

I attached the file for the different in .qip in different version of Quartus.
