Generating xml messages from flatfile

I have a very simple flat file with several rows of comma separated data 
records.  I have used flat file schema wizard to generate the a schema.  I

created a simple pipeline with just the flat-file disassembler component 
that has the generated schema as the do***ent type.  I use that pipeline
on 
the receive ****t configured with a FILE adapter and then on the send side
I 
use a FILE adapter to simple output the message(s) to files.

I was expecting several xml files, one for each row of data in the 
flat-file.  Instead what I get is one message with the root as the 
collection type.  For clarity I am including the generated schema, the
input 
file and the output file.

What I was hoping to get was 3 files, each containing a single record.  I 
was further hoping that BizTalk would assign a single InterchangeID to all

of the 3 messages and each message will have a unique message id.  This is

im****tant because my files can contain over a million records and have a 
single XML message with all the individual messages bundled in would be
too 
lareg to process.

Can you please advse me on what to do to make Biztalk generate an
individual 
message for each record in the flatfile, with all messages being part of
the 
same Interchange.

Thanks.
