[Pw_forum] Did the wfc file must output during the calculation?

Dear all,
    I had a little question about the wfc file. We all know during the  
igk.* file companyed with the calculation. I had a confused about did  
the wfc file must output during the calculation? Because the output  
wfc file was too big to disk space about 100G. That situation cost a  
lot of disk space. So I wondering to know that is there any parameter  
to control the output wfc file.

Thanks a lot!
