single output file with defined name

[Nguyen Huu Chuong]

Hello,
I am still learning how to use cp2k and I would like to print the
forces in a single files with the name "work.frc". However at every
run I get lots of small files:
PROJECT-1.restart
PROJECT-1.restart.bak-1 to PROJECT-1.restart.bak-3
PROJECT-BFGS.Hessian
PROJECT-RESTART.wfn
PROJECT-RESTART.wfn.bak-1 to PROJECT-RESTART.wfn.bak-3
PROJECT-pos-1.xyz
PROJECT-work.frc-1_0.xyz to PROJECT-work.frc-1_13.xyz

What is wrong in my input file?
