#
Filesystem API

The `HfFileSystem` class provides a pythonic file interface to the Hugging Face Hub based on `fsspec`.

##
HfFileSystem

`HfFileSystem` is based on fsspec, so it is compatible with most of the APIs that it offers. For more details, check out our guide and fsspec’s API Reference.

###
class huggingface_hub.HfFileSystem

< source >

( *args **kwargs )

Parameters

- token (`str` or `bool`, optional) — 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.

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

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.

Usage:

    >>> 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)
