## What is it?

Expo creates a `.expo` folder in each project (next to `app.json` or `app.config.js`/`.ts`) for local settings: device lists, development server information and generated types. It is machine-specific and not meant to be committed. Usually small.

## What happens if you delete it?

Expo recreates it the next time you run `npx expo start`. Nothing important is lost; you may need to pick your device again.

## How to remove it properly

Stop the Expo dev server, then move the `.expo` folder to the Trash in Finder.
