# atoti.Hierarchy.folder

#### *property* Hierarchy.folder *: [str](https://docs.python.org/3/library/stdtypes.html#str) | [None](https://docs.python.org/3/library/constants.html#None)*

The hierarchy folder.

### Example

```pycon theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
>>> table = session.create_table("Example", data_types={"Product": "String"})
>>> cube = session.create_cube(table)
>>> hierarchy = cube.hierarchies["Product"]
```

By convention, the \ separator denotes nesting:

```pycon theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
>>> hierarchy.folder = r"some\sub\folder"
>>> print(hierarchy.folder)
some\sub\folder
```

```pycon theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
>>> del hierarchy.folder
>>> print(hierarchy.folder)
None
```
