You can do either of two things:

- specify exactly which products you want to get (which I believe is what
  you were referring to when you said you think you already know the
  answser)

- specify which products you do not want to get.  Please review the
  LDM webpage on extended regular expressions:

As you are indicating, your third option is to not process the files even
though you are receiving them.  This is the best way to do things if the
machine is relaying the data to downstreams who may want the products that
you don't.

Try playing around with fashioning an extended regular expression for
the products you want/don't want after reviewing the web page above.
Let us know if you run into any snags.

Cheers,

Tom
