To add to the possible methods, here's what I do:

I do the minimal install of the annual update. Then I use my file manager program, Total Commander. It's like the old Norton Commander. I paid some fee in 1997 and it's still free, despite several updates per year.

Then I sort the RealTracks folders by date on the new supplied PG Music drive, select the new ones I think I will use, and copy them to the destination folder where I keep the RealTracks. This takes maybe 10 minutes tops each year.

Then I go deeper into the /bb folder and find any style files,.bt0 files etc. and copy them over. Another few minutes.
