The primary Windows SIF default name is ‘winnt.sif’. If the Windows installer cannot locate the primary Windows SIF file, the installation process will not continue.
Moreover, if it is missing, the installation disk or the optical drive may cause an error.
When this happens, the installation disk or the optical drive must be cleaned or replaced. The files using the SIF extension may also be called as the answer files.
