George, you can parallel either format (csv or fixed length), Fixed length is much faster as the system will not have to scan the data to find out the ',' to delimit each field.

thanks for all the advice so far.
currently the idea was to make the file comma deliminated.this makes for a smaller file.
From reading the comments this would not imply fixed length implying i wont be able to paralize it. comment?
