To check data files using EDP Express, follow these steps:
1.Load the desired format file using the ellipsis button to browse to the appropriate file.
2.In the Data File tab, use the ellipses at the end of each row to browse to the appropriate data file you would like to check.
3.Once all of your data files have been loaded, click the Error Log button 
to view the resulting error log. This will open a file that contains a complete list of the errors.
