+**i) fs-extra**
+
+`fs-extra` contains methods that aren\'t included in the vanilla Node.js fs package. Such as recursive `mkdir`, `copy`, and `remove`. It also uses graceful-fs to prevent `EMFILE` errors.
+
+**Installation**
+
+```bash
+npm install fs-extra
+```
+
+**Usage**
+
+```js
+const fs = require('fs-extra')
+
+
+// Async with callbacks:
+fs.copy('/tmp/myfile', '/tmp/mynewfile', err => {
+  if (err) return console.error(err)
+  console.log('success!')
+})
+```
