Compiling PF won't work if file exists

I can't figure out how to get Code Designer to compile a physical file
if it already exists.

 

If I delete the file first, it will compile just fine, but if I compile
again, it fails because the file exists.

I don't seem to have this problem with display files. 

 

Is there a setting I've missed ?  I couldn't find any relevant options
on the compile parameters.
