Can I include the full path to my data file in the header on my reports?

You can change the code for headers and footers in Page setup, available in the Reports menu on the Print Preview window. In the Report header text box, there are codes for changing your report format. Notice that you may have to scroll to see the entire contents of the box. The on-line Help topic 'Headers and footers' contains a list of the codes. In the header text box for your report, locate the code line &D &t&b&b&f. In the case you describe, the "f" at the end of the line means "Include only the name of the file being used in this report." If you change it to upper case "F", it will include both path and filename.
