You have two ways of keeping your USB harddrive up to date.
Method 1
Use the install files you downloaded to update the drive. You just need to change the install directory to reflect the drive letter of the USB drive i.e. C:\bb to e:\bb if e: is the USB drive letter.
Run all the install files that you received this will update the program, realtracks and all support files.
Method 2
Copy the \bb and \RealBand folders from your c:\ drive to the USB drive and overwrite everything or firstly delete the \bb and \RealBand folders on the USB hardrive and then copy the folders across from your harddrive.
Both methods will update the files on the harddrive to the 2017 version.
Once this is done the \Documentation folder can be updated with the latest and pdf manuals which are found in the \bb directory.
The \PGMusic folder can be updated by copying the installation file for BIAB and RealBand.
Hope this helps your endeavour.
