It wouldn't matter if the answer was really found.

I have tried this between Limewire and Frostwire and this doesn't work. I also tried asking the advanced question of how I would go about configuring the .dat file to accept it but never got an answer.

If sure it isn't as hard as it seems, but I did not want to mess up my .dat folder and maybe risk loosing the other incompletes. In the end I just just deleted the incompletes but would still like to know if rewriting the .dat file could work
