We use (and love) Graham's process_pdata script to delete the spectra.
Its almost a disk doubler. Lately some large plotfiles (from xedplot)
have landed in pdata so I've added this line to his script to get rid
of these:
find /diskname/data/*/nmr \( -name plotfile.????.ps -o -name
plotfile.???.ps -o -name plotfile.??.ps -o -name plotfile.?.ps \)
-atime +$ndays -exec rm {} \;
hope this helps,
