I never tried to, but it seems like you could launch them both. However, computer basic basics apply, and you can't do anything with a file that is "open", and that would be the snag. Like you can't rename an MP3 while it is being played in media player because it is "open". When the file is in BIAB it is open. You need to close it so the program sets the end of file marker before you can open it again.
