File Poll operation Batched Output

Hi,
My requirement is that i want the File Poll operation to give me the file contents line by line.Iam using the File Poll operation with Batched Output option checked and No of lines with 1.If suppose my file contains 100 lines 100 documents will be published.The pdf says that processing files in batch is always good.In this particular case instead of publishing a single document it publishes 100 documents.Is it not a overhead?.Can someone throw some light on this?.
Or do i have to use a File Read operation after my Poll operation to give the contents line by line?.

TIA,
Balachandar.

where do document types get stored when u save them in enterprise integrator.

?

I used the Delimlited Input operation after the File Poll. This operation parsed the data line-by-line and reduced the overhead.
