Certain versions of Adobe Acrobat and other PDF editing software allow the user to save a fillable form after data has been entered, and edit that information at a future date. If a form with saved data is filed electronically, (by someone with internet filing privileges in CM/ECF), the data can be easily extracted. To "flatten" the electronic file (i.e., to make the field data indistinguishable from the rest of the text in the form), "print" the form to PDF (using the print dialogue box), and file the resulting document.
