If I am using the flashcard to download books from Bookshare, the extension is bks; when downloading web braille books, my extednsion is brf and I never get truncated files. When asked about reviewing options on the BrailleNote I always say "no." Although I use my BrailleNote for other chores, my main use is to read books and I have never had the problem you are talking about. I assume you are reading in braille. And, of course, when downloading from Bookshare, I use the brf option. HTH.
