Your plan sounds fine except your step 2. I don't see why it is necessary to delete the files. If I understand correctly, you essentially have a 2017 audiophile on your internal D and E drives? I'm assuming you've made changes to the program on your D and E drives, and you are thinking that you want to preserve the changes and that to do so you need to copy the entire thing. I would suggest instead that you copy just the bb folder files over. The RealTracks and Drums folders should be almost identical (unless I'm misunderstanding your question), you could copy them if you want and tell Windows to skip files that already exist. Also, showing hidden files and folders would not be necessary, in fact that might cause problems since Windows will complain if you try to delete a hidden system file.
