Common folder for All Users

Hello,

I need a common folder for both admin and standard user where my application can put its common files.

Problem is that standard user is only able to read and write in Documents folder, though admin is able to write data at many other folders like library. But i am not able write in Library when my application run from standard user.

So please help me how to find a common path from where i can read and write from my application from admin and standard user as well.

Thanks,
Ruhi.
