Hello,
The system has changed to better suite the switch between Simulation and Real PLC,
and to secure the Filesystem on PLC and on your Windows PC aswell.
If you want to have a common Directory i think there is a posibility to use the upward change dir ..\ ; in the past i have used it to access a Directory in my Logical View.
I think this could still work. But you have to try it.
This example leads to the Folder CFFiles in Root of Logical View.
With some adaption you may get up to the C:
Good luck in Testing.
Greetings
Michael
