Thanks, I just discovered this. Now I know you can do that and just drag the files across using the PC remotely it makes more sense.

Apologies to all, I'm dealing with two things at once as I've been a Mac user for 20+ years now, but my MBP is currently off being repaired so I'm on an old Windows laptop - so trying to find my way around how Windows works with networking, formatting drives, etc. at the same time as getting my head around how to do this in ROCK.

Think I've got how I'm trying to do it now!
