There's no way to do what you want with an EXEC action.  The PIPE action does 
have an (undocumented) "-metadata" option that passes binary metadata 
information to its decoder, but nothing like that is available to the EXEC 
action.

One workaround would be to have a "FILE -close" action just before the EXEC 
action that filed the same data-product.  The name of the file could be passed 
to the EXEC action, which could take the size of the file.
