there are various solutions available to you, depending on the hardware you have available or the budget you have to spend. The simplest solution (and cheapest) would be to use a Parallel File transfer cable and the DCC software native to windows. Unfortunately that is very slow. The best, fastest performing solution would be to network them which could be a bit technical and expensive if the machines are not alresdy eqipped for this. A third solution is to use a USB data tranfer cable and the third party software to run it, this is good solution in terms of ease of use but again is fairly expensive.
