No idea! Smile, but I will say that that book had a lot of formatting, a lot of bold, italics, and underlining, so perhaps? Braille doesn't contain those kinds of formatting and I know that they take up space. Though, smile, let me check. Mine the .rtf has 735 Kb as its size. I suspect the mark up takes a lot, but I can't imagine that much. maybe John should look into it. has anyone downloaded it, does it behave properly? Shelley L. Rhodes B.S.
