Thanks M'Lord. What's with the funny penguin?

From your reply I gather I'll go back to the default LW Shared Folder, and have the files also transfer to iTunes. Then I will move the iTunes files to my external hard drive, as a backup. And keep the files in the LW app/music folder as the Shared Folder, open to all. Maybe I'll edit and delete down to a manageable size. And maybe I'll share other folders, as you do. I'll read the optimising hints you recommended, too. Thanks for your advice.
