Sysprep default answer file location in GSS 3?

I need to create a custom sysprep answer file for deploying an image. I want to add the copyprofile=true entry.

I would like to take the GSS3 default answer file that is used, make a copy of it and add the info we need. Where is the default answer file stored on the ghost server? I am looking for the Windows 7 Profesional X64 Sysprep answer file.

Thanks
