First, you should create jupyter_notebook_config.py in the path (C\Users\yourname\.jupyter).

Second, find the following item in the config file:

## The directory to use for notebooks and kernels.

c.NotebookApp.notebook_dir = 'D:/JupyterLab'

Finally, you change the default directory that you want to use.

Enjoy it.

Hi Bhat

This link of QA may help you: https://stackoverflow.com/questions/35254852/how-to-change-the-jupyter-start-up-folder

Thank you everyone for your responses. This is how I did it.

1. From current working directory type

cd folder path

2. After entering in that directory simply type jupyter notebook.

Your notebook window is opened in that directory.

That will spin an instance of Notebook in that specified directory only.

Thanks.
