Linda: While I can't give you the programmer's explanation, this sort makes sense for several reasons: 1. In the case of the Daisy books that come from RFB&D, the CD has to be in place. 2. In the case of Book Share or other Daisy files, the way that it works is that even though you're only transferring the one "OPF" file, it looks ta t the other files in the Daisy book to get the information. Besides, you wouldn't want to tie up your hard drive or Temporary file with all of that, as Daisy files can be quite large. So, while I can't explain it all technically, I can tell you that this makes sense that it is this way.

He has put daisy formatted books on there before. What's the reason for this message and not being able to transfer some daisy books and not others?
