# Filesystem API

The `HfFileSystem` class provides a pythonic file interface to the Hugging Face Hub based on [`fsspec`](https://filesystem-spec.readthedocs.io/en/latest/).

## HfFileSystem[[huggingface_hub.HfFileSystem]]

`HfFileSystem` is based on [fsspec](https://filesystem-spec.readthedocs.io/en/latest/), so it is compatible with most of the APIs that it offers. For more details, check out [our guide](../guides/hf_file_system) and fsspec's [API Reference](https://filesystem-spec.readthedocs.io/en/latest/api.html#fsspec.spec.AbstractFileSystem).

  A valid user access token (string). Defaults to the locally saved
  token, which is the recommended method for authentication (see
  https://huggingface.co/docs/huggingface_hub/quick-start#authentication).
  To disable authentication, pass `False`.
- **endpoint** (`str`, *optional*) --
  Endpoint of the Hub. Defaults to <https://huggingface.co>.</paramsdesc><paramgroups>0</paramgroups></docstring>

Access a remote Hugging Face Hub repository as if were a local file system.

> [!WARNING]
> [HfFileSystem](/docs/huggingface_hub/v1.0.0.rc6/en/package_reference/hf_file_system#huggingface_hub.HfFileSystem) provides fsspec compatibility, which is useful for libraries that require it (e.g., reading
>     Hugging Face datasets directly with `pandas`). However, it introduces additional overhead due to this compatibility
>     layer. For better performance and reliability, it's recommended to use `HfApi` methods when possible.



<ExampleCodeBlock anchor="huggingface_hub.HfFileSystem.example">

Usage:

```python
>>> from huggingface_hub import HfFileSystem

>>> fs = HfFileSystem()

>>> # List files
>>> fs.glob("my-username/my-model/*.bin")
['my-username/my-model/pytorch_model.bin']
>>> fs.ls("datasets/my-username/my-dataset", detail=False)
['datasets/my-username/my-dataset/.gitattributes', 'datasets/my-username/my-dataset/README.md', 'datasets/my-username/my-dataset/data.json']

>>> # Read/write files
>>> with fs.open("my-username/my-model/pytorch_model.bin") as f:
...     data = f.read()
>>> with fs.open("my-username/my-model/pytorch_model.bin", "wb") as f:
...     f.write(data)
```
