when you create the Flat File source connection, you can state that the first row is a header record so that will remove the header row. (you can also state how many rows to skip out of the file in the event that the header takes up multiple rows)

the footer is not as simple. is your footer record formatted the same as the body of the data? meaning, if the body of the data is comma delimited, is the footer row the same or is completely different with just textual information?

if it is completely different, if you do the data transform from the Flat File Source into another Data Flow task, the footer record may drop out, from my test it did, but I am not completely sold on this. I would want to handle the bad row in my error handling of the Flat File source to do something with the bad footer record.
