google colab( jupyter ) , it is slowly to unzip, why, and how to make unzip quickly?

```
import zipfile
with zipfile.ZipFile("drive/app1/train.zip","r") as zip_ref:
zip_ref.extractall("drive/app1/targetdir")
```

The issue provides only a Python zipfile snippet and does not name a repository file, test, or notebook entry point. Start by reproducing the extraction in Google Colab and compare it with the expected behavior; the issue would need a defined project-side cause and acceptance criterion before a contribution can be considered done.
