My books have the DRM stripped when I found that the DRM applies only to a particular reader app; which is why Calibre doesn't have all the books in its catalog/library.
When I said "extension", I was wondering if CC has its library in internal storage & when "full", extend or continue the library on the external sdcard; the alternative is the library will be in the internal storage or external sdcard. This isn't a case of using the external sdcard configured as part of internal storage in the Marshmallow configure option.
When I do the ebook directory backup, I make 1 copy on the pc, then 1 copy on the nas, & then 1 copy onto an external usb3 4tb drive. The usb3 4TB drive is really for backup of the 3TB nas drive. I just do a copy of the ebook directory; don't need to copy the books individually.
