Help Add H5 extensions

[Musically]

Hello

I am facing a problem adding some things to the private server (PVP Zone - NPC Buff ......)
Of course, I found her files here on the site, but when I follow the steps, I cannot find the correct path; Does every server have a private path or there is another reason I do not know.

I hope for a reply anything useful, my servants are H5
.........................thank you
