App.js file is alwaysThe components are created as Jsx files in src folder during react-app project creation. Try moving it there, if it is replacedyour folders. Components will remain in components folder in srcTry using-
import Header from "./Components/MiscComponents/Header.jsx"; import Users from "./Components/UsersDisplay/Users.jsx"; import User from "./Components/UsersDisplay/User.jsx"; import Login from "./Components/MiscComponents/Login.jsx"; import EditOrCreateUser from "./Components/CreateEditUser/EditOrCreateUser.jsx"; Only 'js' files take automatic imports without mention. Then, these importsThis should work fineI think.
