[[Errno 13] permission denied]

I have tired to download a file from Yeggi as a .stl and convert to g-code.  when I try and save it to the sd card it gives me the error:  Could not save to E:/UM2_Karambit divided half .gcode [Errno 13] permission denied E:/UM-2 Karmabit divided half.gcode

 

My read only is up on my card and I have tired several cards all with same error.
