I have been here before. The easiest way to do this is to pull the drive and set it up as a slave on the other computer. Seems kind of drastic but as long as the other computer is set to boot from the master it works slick as snot on a cold Idaho day.
Take your file and paste it and turn of the machine and put it back.
