# Single-File Download

> Download a single file from the filesystem.

This endpoint downloads one file from a filesystem by relative path.

Use it when you want file bytes for a single path such as `output/report.md`.

## SDK Surfaces

### TypeScript

```typescript theme={"dark"}
const response = await client.filesystems.downloadFile({
  filesystem_id: 'fs_123',
  path: 'output/report.md',
});
```

### Python

```python theme={"dark"}
chunks = client.filesystems.download_file(
    filesystem_id,
    path="output/report.md",
)
```

If you need the entire filesystem instead, use [Get Download URL](/api-reference/filesystems/get-download-url) or `tu fs pull`.
