Here goes a dumb question
 

I have some files that I've had in my incomplete folder for awhile and I was wondering if I leave Limewire on will they pick up from awaiting sources status when someone logs on with the files to share?

You need to resume the files .. then they will apear in the download window, probably awaiting sources, after searching for them, but with luck they may restart downloading.

Re-searching them increases the chances of them resuming, I find, as if the search turns up the same file it can kick start it into action:)

It is not a good idea to resume more than a few files at once.

I hope this helps :)

I was wondering since I'd never saw one start without I had found it again.

They should restart if the sourse is out there, but in practice it often does not happen ..ofter starting again is the best policy:) Just remember they will never restart if just left in the incompletes with out being in the download window
