<span id="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.

```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"]
```

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

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

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
```
