I just put up a new version. The previous one would crash on loading a destination file if it was not perfect. New checks have been added that should be able to handle all manner of errors. Please write or call with questions on how to use this new feature. Currently Android will prompt you to use VFR in strange circumstances. If this is a problem. Use the prompt and after setting the proper app to run on your file, select the option to always use this app in the future.
