dbpoweramp batch converter is one of the program that comes with illustrates dbpoweramp (along with CD ripper). Find it in the illustrate/dbpoweramp folder in your programs using windows explorer (called DMCfileselector). Once you find it, start it (double click on it) and once it comes up you can navigate to the top folder of your music files in the left side box, and tick on that folder that to select. then follow the rest of the instructions I gave you. See pic. (p.s. experiment on maybe one album first just to test things rather than selecting ALL your albums).

p.s. I never see your pictures. They are always pending for a few days (because you seem to post too many for the forum and it limits their availability to others temporarily). By the time they are available, I've moved on to other things so they never actually help me answer your questions. I suspect you post too many pictures. You should stop and consider whether a picture is specifically necessary when posting vs always posting lots of pictures.
