Jim,

Is this a one-off? Or an ongoing operation?

If the latter, I should strongly suggest you consider purchasing an MGPART1 license, also known as Partitioning Lite, 5-threads — well-under a thousand USD, the last I had need.

Then you can call it from the command-line; or from another Magic operation with Call Remote, anywhere on the network; or schedule tasks using Windows Task Scheduler. It does NOT accept http requests, so it's secure by virtue of it's ignorance.

If the former, why not just use the runtime? Why does it need to be the Studio? If it NEEDS to be the Studio, then look into the "Tools Infrastructure" topic and its "Automatic Processing" subsection. It's in the online Help.
