# How to Configure Your Rust Dedicated Server (server.cfg) (/docs/rust/server-config)



import { File, Folder, Files } from 'fumadocs-ui/components/files';

Rust uses startup parameters AND `server.cfg`. The cfg file takes priority over startup params.

<Files>
  <Folder name="server" defaultOpen>
    <Folder name="server1" defaultOpen>
      <Folder name="cfg" defaultOpen>
        <File name="server.cfg" />

        <File name="users.cfg" />
      </Folder>

      <File name="proceduralmap.sav" />

      <File name="player.blueprints.db" />
    </Folder>
  </Folder>

  <Folder name="oxide" defaultOpen>
    <Folder name="plugins" />

    <Folder name="config" />

    <Folder name="data" />
  </Folder>
</Files>

The `server1` folder name is set by `+server.identity`.
