# 파일 시스템 API[[filesystem-api]]

[HfFileSystem](/docs/huggingface_hub/v1.24.0/ko/package_reference/hf_file_system#huggingface_hub.HfFileSystem) 클래스는 [`fsspec`](https://filesystem-spec.readthedocs.io/en/latest/)을 기반으로 Hugging Face Hub에 Python 파일 인터페이스를 제공합니다.

## [HfFileSystem](Hf파일시스템)[[huggingface_hub.HfFileSystem]]

[HfFileSystem](/docs/huggingface_hub/v1.24.0/ko/package_reference/hf_file_system#huggingface_hub.HfFileSystem)은 [`fsspec`](https://filesystem-spec.readthedocs.io/en/latest/)을 기반으로 하므로 제공되는 대부분의 API와 호환됩니다. 자세한 내용은 [가이드](../guides/hf_file_system) 및 fsspec의 [API 레퍼런스](https://filesystem-spec.readthedocs.io/en/latest/api.html#fsspec.spec.AbstractFileSystem)를 확인하세요.

- **endpoint** (`str`, *optional*) --
  Endpoint of the Hub. Defaults to .
- **token** (`bool` or `str`, *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`.
- **block_size** (`int`, *optional*) --
  Block size for reading and writing files.
- **expand_info** (`bool`, *optional*) --
  Whether to expand the information of the files.
- ****storage_options** (`dict`, *optional*) --
  Additional options for the filesystem. See [fsspec documentation](https://filesystem-spec.readthedocs.io/en/latest/api.html#fsspec.spec.AbstractFileSystem.__init__).

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

> [!WARNING]
> [HfFileSystem](/docs/huggingface_hub/v1.24.0/ko/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.

The file system supports paths for the `hf://` protocol, which follows those URL schemes:

* Models, Datasets and Spaces repositories:

```
hf://<repo-id>[@<revision>]/<path/in/repo>
hf://datasets/<repo-id>[@<revision>]/<path/in/repo>
hf://spaces/<repo-id>[@<revision>]/<path/in/repo>
```

* Buckets (generic storage):

```
hf://buckets/<bucket-id>/<path/in/bucket>
```

Note: when using the [HfFileSystem](/docs/huggingface_hub/v1.24.0/ko/package_reference/hf_file_system#huggingface_hub.HfFileSystem) directly, passing the `hf://` protocol prefix is optional in paths.

Usage:

```python
>>> from huggingface_hub import hffs

>>> # List files
>>> hffs.glob("my-username/my-model/*.bin")
['my-username/my-model/pytorch_model.bin']
>>> hffs.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 hffs.open("my-username/my-model/pytorch_model.bin") as f:
...     data = f.read()
>>> with hffs.open("my-username/my-model/pytorch_model.bin", "wb") as f:
...     f.write(data)
```

Specify a token for authentication:
```python
>>> from huggingface_hub import HfFileSystem
>>> hffs = HfFileSystem(token=token)
```

- **path** (`str`) --
  Path to resolve.
- **revision** (`str`, *optional*) --
  The revision of the repo to resolve. Defaults to the revision specified in the path.`HfFileSystemResolvedPath`Resolved path information containing `repo_type`, `repo_id`, `revision` and `path_in_repo`.- ``ValueError`` -- 
  If path contains conflicting revision information.
- ``NotImplementedError`` -- 
  If trying to list repositories.``ValueError`` or ``NotImplementedError``

Resolve a Hugging Face file system path into its components.

- **path** (`str`) --
  Path to the directory.
- **detail** (`bool`, *optional*) --
  If True, returns a list of dictionaries containing file information. If False,
  returns a list of file paths. Defaults to True.
- **refresh** (`bool`, *optional*) --
  If True, bypass the cache and fetch the latest data. Defaults to False.
- **revision** (`str`, *optional*) --
  The git revision to list from.`list[Union[str, dict[str, Any]]]`List of file paths (if detail=False) or list of file information
dictionaries (if detail=True).

List the contents of a directory.

> Note: When possible, use `HfApi.list_repo_tree()` for better performance.
