You might want to double check with PG Music tech support, but if you have the UltraPak you will not need to install all those numbered RealTracks or shots/holds. You will want to install the UltraPak then whatever XtraPaks, 49-paks, artist performances, and Bonus Paks you have. Don’t forget to preserve any of your song files and custom styles you may have made.

I’m surprised you have all those individual RealTrack install EXE files. Is it possible you were a beta tester?

I respectfully but completely disagree with the advice that the program and RealTracks should be on the same drive. That’s the first I’ve heard that opinion in 12 years discussing the subject. I can tell you mine are on different drives, and work great. If they needed to be on the same drive, the program wouldn’t make it so easy to split the locations and specify them during install, or change afterward.

The installer will ask you where the program goes and where the RealTracks go (also where the RealDrums go). That could be as many as three different drives.

There will be a very few small files that must still be written to your boot drive, such as fonts and activation, but they shouldn’t pose any size problem.

Finally, your USB drive will work fine for BIAB, but if you have room in your case for another hard drive, any internal SATA drive would be faster than a USB drive.
