Yes, in theory you can combine all your existing material by copying it to another location where BIAB is installed. Make sure whatever copying software you use will overwrite only older dated files.

I do this every year.

HOWEVER in BIAB 2018 they substantially changed the folder organization. If you are trying to recover files from 2017 or earlier onto a drive with BIAB 2018 or later, it won’t work directly. I urge caution and suggest you call PG Music Support for guidance how to proceed. Be prepared to detail everything you have and exactly what you want to do.

While I and several other fellow users have the experience and skill to do this, we cannot take on the responsibility of guiding you here in case something goes wrong.

ps ever run into Steve Dillard in San Diego? Great trumpet player.
