iTouch 4 problem with importing CSV file

I have both an iTouch 1 & 4. I am trying to import a CSV file of my favorite RTK stories for my Anki/RTK apps. I was able to do this with older iTouch-1st generation without any problems. The 4th generation iTouch can't read the CSV file and mistakes it for an Excel file or something. I used to be able to import the CSV files, but I haven't had any success in recent months.

Any solutions?

Thanks...
