Now that is a joke.
Again, I have a desktop PC with around 1tb storage so that doesn't bother me, if I want a file on it, just use the local WiFi. As for 20gb out of 32gb used, come on, he either used windows 10 home or pro/Enterprise. I used windows 10 ltsb and it worked like a charm and was able to fit 10-11gb of data
