Hi; My apologies if this seems a bit basic but I was trying to do something that should have taken five minutes and well here I am. I have converted some openbook files to txt files. I then made a bookport folder and tried simply copying them into the folder. Although the titles copied when I tried to listen to any of the files I get the dreaded "playing unfiltered files not supported". I initially thought that the txt files might not have been converted correctly but they open and read quite nicely with notepad. Any ideas are welcome. Richard
