limewire settings backup question

Every so often I'll wipe my hard drive and reinstall everything fresh. So this means I have to rebuild my library everytime I do that and sometimes I don't for a long time because it eats up so much RAM and takes like an hour or two in the case with larger files. If I were to save the .limewire folder where the settings where saved, would LW not have to redo this whole process over again with the exception of a couple file changes perhaps? Or is there a particular folder or file within the .Limewire folder that stores that info?
