Can my file contain headers and/or footers?

Yes and no. To avoid errors, you must enter the number of headers and/or footers on the Upload Files page in Web Upload. Examples of headers and footers include field names and column summaries. Please note that headers (as the name implies) occur at the beginning of the file. Footers occur at the end of the file. If this information is repeated in other areas of the file, these are considered fillers. Header/footer information should not be used in the middle of the file as often occurs in some software packages.
