Need to copy a 200GB directory

[R. Anthony Lomartire]

Also sorry idk if there is an intro thread or anything, but I've been a
lurker for a while this has been my first actual post I think. I don't know
if I should reply all or just send my reply to the GNHLUG email address?

Anyways just quickly, I'm Tony and I'm in ad tech. We use machine learning
to help advertisers optimize their ROI. At first I thought it would be
lame, but at least it was a job, but gradually I have become more and more
interested in ad tech and it is actually kinda cool. Ok so hiii!
