If the app already has a layout, follow its existing conventions and leave files where they are — a default to start from, never a standard to enforce or migrate toward. When unsure whether a project is new, ask before moving anything. The whole layout, assembled from the rules below: Keep app code under src/ to separate it from config files. Expo Router supports both app/ and src/app/ out of the box — to switch, move the folder and restart the bundler. The default template aliases @/ to ./src/ in tsconfig.json. src/app is routes-only: every file there becomes a route, so nothing else belongs in it. Everything below lives in sibling folders. Generic, reused UI (button, card, table) with one named export each. Name files in kebab-case (bar-chart.tsx), matching the default create-expo-app template. When a component grows, give it its own folder with the root in index.tsx and colocate its private sub-components beside it — the import path (@/components/table) stays unchanged.
