not sure--I think it stores the info about incomplete downloads, particularly swarmed downloads and maybe the "alernate sources". I've got a record number of uploads going on right now, so I don't want to risk looking in it just now. Could you look at it with textedit or bbedit maybe? I'd look for IP's and maybe some kind of allocation map for the chunks

I read somewhere that "there's unfortunately no way to tell which incomplete files are having problems. You should probably simply delete your downloads.dat file, unfortunately."

btw--if my previous post made you mad--sorry: I was getting silly and thought you'd enjoy it. Let me know and I'll edit it.
