Have you tried dropping the folder-full-of-files on top of the Converter app?
I does not mention that in the documentation and it is not an app but a bash script fmdbconverter.sh, but I will try it anyway.
Update : No drag and drop support, so only a command line tool

So to execute multiple conversions listed in my convert.sh file do this:
sudo chmod 755 convert.sh
And then to execute the file:
Hope this helps someone else in the futre.
