After upgrading to BIAB 2018 I decided to prepare for the inevitable growth of BIAB per annual release, therefore opting for a 1 tb xternal drive for use of the program. I did a "copy and paste" waited a few long hours for the transfer. All seemed ok until trying a few styles when the yellow splash screen indicated there are missing files. What is a sure way to move the PG music products to a new drive without having issues with missing files?
