Yah, that used to be a good trick to save some pesky incompletes, but now downloads.dat is stored in the ~/Library/Preferences/Limewire folder.

I also see a Library.dat file . . . perhaps the two are related. No sign of downloads.dat any more, so perhaps it has been deprecated.

For a definitive answer, you could ask in the developers' forum at LimeWire Forums

thanks for that.
i see the files you mention.
Would anyone know what files i would need to move along with the incomplete files themselves so that i may return to those incom files at a later time?
