A strange question perhaps but looking at the contents of a book folder how would you determine whether it was or was not a daisy BOOK? Putting it another way, if it contains .smil files and an ncc.html file along with mp3 files, would it not be a DAISY book? I ask this because it is being suggested that a particular book of this construction will not read within the Go Read app because it is an MP3 book. Peter
