Thanks for your help, I’ve been really busy the last few days, hence my late reply.
The file loading issue sorted itself out after a couple of days. Typical computer stuff: problem has no apparent cause, resolves itself somehow over time and restarts.
I do need help with the folder share. I followed the instructions that you gave me previously with no luck. In the meantime I did run a LAN cable to the Discovery (in lieu of the wifi link) so that might help.
