Mike I generally download the brf files from bookshare. Occasionally there will be annoying Braille translation problems in these files. If the problem gets on my nerves too much I go back and download the daisy file. One book I had in brf from bookshare kept reading quotes as his and was. Needless to say, that was intolerable. I think I have only replaced two brf files with the daisy version so far. The other one had some recipes which were not reading correctly in the brf version. The daisy books unpack into multiple files so I just find it quicker and easier to use brf unless there are problems as mentioned above. Joni
