Right now there is code to copy a file from the reader to the PC, but it isn't working, and I haven't figured out why. I figured I'll make what I have done available as it should be very close to having that work; someone might see the error and point out a fix. I haven't written C in about 4 years so I apologize if the code is dumb.
I wrote this in VS.Net 2005 so the project file requires that but it would be easy to adapt; its pretty straightforward C (although some compiler may barf on the zero-size arrays).
