Go is just a language. Surely any language can be used to enumerate network resources, tickle an API or twiddle some counters.
"Files Go" is part of "Android Go" which is about being lightweight and fast for more modest hardware -- doesn't have anything to do with the Go language.
Ah, I see. I was thrown off by the naming. Thankyou for the clarification.
