Thanks.
Given that I don't have Google Drive I've tried to share them (on the Samsung) via bloetooth for sending them to the Asus.
Doing that, on the Sansung I could choose text, snb or vnt.
With 'text' I had only one file, with all my notes in it, so I tried 'snb'. I had 48 files and it seemed I could import them on the Asus Supernote, but when I selected them I got the messaghe 'file corrupted'. The 'vnt' files weren't readable on the Supernote...
Nothing good then...
