Thank you kindly for your response and sorry to have bothere you with such a basic query.
I was referring to how I get my downloaded material from LimeWire to I-tunes, I have managed to do so, by saving playlist elsewhere, however despite this when I'm deleting files from Lime Wire they then cannot be found on i-tunes again as the original source is not available. As I'm using the windows version the preferences option you refer to is unavailable. So sorry, but completely lacking in knowledge!!
