Convert all files to PDF
If you use any of the files that are not PDF (e.g., .txt, .xmef, .ptx), they must be converted before e-filing. This can be done by “Printing to PDF” using a program like Adobe Acrobat Pro (commercial) or Cute PDF (free).
Files can also be converted by printing out the document, and then scanning back into the computer; “Scanning to PDF”. The latter method will result in a slight quality loss and potential removal of OCR data.
