Remove the File Test column

[Nick Camaldi <willowbrookmagic (at) hotmail.com>]

So I have no data coming in on the files column and I would like to remove it from the display. 
 
While searching I found this:
 
I don't want to display column foo in my display. How do I do that ?
A. Add the entry NOCOLUMNS:foo,bar to hide column foo and bar.
 
so my command would be 
 
NOCOLUMNS:files
 
Is this correct and which file do I add it to?
