Yes, the error trapping isn't anywhere near perfect yet, so in case of an "Out of memory" error the program window doesn't display the message. The parameter "-Xms32m" means that the initial heap space (whatever it is) is 32MB(?) and "-Xmx256m" means a maximum heap space of 256MB. If you still manage to get errors you can use even higher numbers for these parameters. Running with these parameters I could extract materials from a 35MB file, and it took only about 2 seconds. I think the double line breaks were already in the HER CR2 file. And they probably weren't double line breaks at all, I think they are Windows formatted line breaks. On a UNIX/Mac system it looks like double line breaks. This app doesn't reformat the text, except the few first lines.
