# pathExists(file[, callback])
Test whether or not the given path exists by checking with the file system. Like [`fs.exists`](https://nodejs.org/api/fs.html#fs_fs_exists_path_callback), but with a normal callback signature (err, exists). Uses `fs.access` under the hood.
- `file` `<String>`
- `callback` `<Function>`
## Example:
```js
const fs = require('fs-extra')
const file = '/tmp/this/path/does/not/exist/file.txt'
// Promise usage:
fs.pathExists(file)
.then(exists => console.log(exists)) // => false
// Callback usage:
fs.pathExists(file, (err, exists) => {
console.log(err) // => null
console.log(exists) // => false
})
```
