is there someway for limewire (or an external program) to read all the files i give it and to somehow rebuild the downloads.dat file so that limewire can continue downloading from where the file has left off instead of starting over again?

i currently have incomplete data that will no longer continue downloading so im forced to delete them

does anyone know of a way to preserve incomplete files and to continue downloading them or have any idea on how limewire knows how much has been downloaded and how to continue where it left off?

thanks =D
