Increase nstxout, nstvout, and nstxtcout.  That will reduce the size of the .trr 
and .xtc, which are likely the largest files that you will be writing.  If you 
want to decrease the .xtc file even more, specify xtc_grps.  If the .log and 
.edr files get out of hand, adjust nstlog and nstenergy.  The -compact flag only 
affects the .log file, and is set by default.
