ValueError: path is on mount 'D:', start on mount 'C:'

Hi, I’m trying to open files on OpenEP from my D drive. Unfortunately, it gives me an error when I do this.

ValueError: path is on mount ‘D:’, start on mount ‘C:’

When I move the folder with the maps to my C drive I’m able to load it up. Does anyone know why this happens/how to remedy it?

Hi Neil, we have not done much debugging using different drives so for now it is probably worth keeping the data and code all on the same drive
