I assume you are using note3 app package.
the note3 snote cannot see the old snote2 files.
open the snote3 app, and manually import them from where they are saved.
OK, I have some files on my computer,
but here's, yet, another question ...
I must confirmed that Gorilla glass on my Note 2, have scratches.
what is sad here ? I WATCH FOR MY PHONE VERY CAREFULLY.
nOT even once ( or maybe once or twice ) it was in my pocket with other stuffs like coins or keys. ž
