Again, many thanks for the clarifications between the functions/features of DS Store
and Volume Directory . . . and how the FOLDER "tree" behaves.
I think I understand now : I changed the window options for my HOME FOLDER. No problem there, but the APPLICATIONS folder within my Home Folder would not take on the new appearance. However, MUSIC, DOCUMENTS, LIBRARY and others did change. So, APPLICATIONS must have its own DS Store file that overrides the settings of the HOME FOLDER (which is higher up the "tree", so to speak).
