plugin/auto: the different zone in directory not work.

[brotherlu-xcq]

I have a zone example.com in Corefile like below:

. {
    auto example.org {
        directory D:\\coredns\\zones
        reload 5s
    }
}

and have 2 zones in D:\\coredns\\zones:

I want to known the popurse of just using the zone in Corefile, not in the directory?

if we just want the zone in Corefile work, why we still load all the zones in the directory?
