Can I create a C: partition on an MK4900?

I have a bank in Santo Domingo that wants to use an MK4900 with an internal .net application but the app was written to pull images from a c: drive PC location but the MK4900 doesn't have a C:drive so they want to know if they could create a C: drive partition on the MK, then load the images there and have the application get the images from that C: drive partition location.

I understand that the application folder on the MK is Non volatile and anything outside that folder will be erases when the MK is powered down. Is that anything else we can do to make this work?

Thank you.
