Using USB port to import data

[bna128]

The goal of my project is to have a portable microprocessor that can convert digital data to analog. In order to accomplish this goal, I purchased an Arduino DUE. Unfortunately, I am having trouble getting files containing the digital data to upload to the arduino through the USB port. I am pretty new to Arduino. Is there anyway to upload digital data to the DUE using the USB port? If not, is there a different method for uploading digital data that you would suggest?
