Reading file from External PC

Hi,

My Yumi robot needs to read a file from external pc hard drive. As I searched in the Application manual Controller software IRC5, the robot can read and write on the external pc using ftp connection. I tried to setup ftp and read a file (.txt) from the path C:\Robot_1 in the pc which is addressed by pc:\ in the robot controller (As discussed in the Application manual Controller software IRC5). Unfortunately, the robot controller cannot see the path and the pc:\ is not added to the Home: of the controller.

I really appreciated if  you help me in this issue.
