I have been able to OCR several files using the OCR demo.  Now that I have the resulting .rdf files, I can't find a demo which will open them - all them ones I've tried say "invalid file format".  What demo should I use to convert the .rdf file to a .txt or .doc file?

The RDF file is not meant to be opened. This is a file the OCR engine uses to store the recognition results. We use this file internally to create the results in the final text file. After you save the RDF file, you should go to "Save Results" in the demo to save the actual text results out to file.

according to the previous thread message, you said that ocr engine uses rdf file to store the ocr recognition result.

So, if I have an rdf file, I can create a new rasterocr and set the RecognitionDataFileName == myrdffile.

Then, the ocr engine can have reference to all the result. Is that correct?

I'm not really sure what you are trying to do, but in this case, if the
RDF file already has data in it, then any subsequent recognitions will
append the new data to the file, so when you save the result, the
resulting file will contain the old data that was originally in the
file and the newly-recognized data.  You cannot access the data in the RDF file otherwise.
