# ROOT\_DIR

The ROOT\_DIR value should be relative to the root of the directory.

💢 Default value: `''`

```
// cypress-image-diff.config.js
const config = {
  ROOT_DIR: 'visual-test/custom-folder-name',
};

module.exports = config;
```

```
    .
    ├── visual-test
        ├── custom-folder-name
