The second step allows you to specify the overall format of your text file.
When you move to step 2 of the File Import Wizard, the first 25 lines from your sample text file are displayed in the Sample data from filename box at the bottom of the screen, to help you verify the way your text file is formatted. If each row of data is very long, you may need to scroll to the right to see all of the information in the row. Blank lines in your text file are ignored on this screen and will also be ignored when the template is processing data.
