When I go to start up mach 3, I go to mach 3 loader, then select the XML file for the DMM breakout board I'm using, and mach 3 then loads up.

I'm using an ESS and 2 DMM breakout boards

I'm adding a c10 board to another port on the ESS. The c10 board has an xml file for it. Its been awhile since I set up mach 3. My question is where do I put the xml file for the c10 board? A certain folder?
