title: Windows Subsystem for Linux (WSL 2) and Jupyter Lab : How to open a Jupyter Notebook saved at the Linux file system?
body: <p>I have a Jupyter lab installed on Windows. I installed Jupyter Lab on WSL Ubuntu. I can lunch Jupyter Lab from Linux terminal.  This will open Jupyter Lab on Chrome browser from which I can start a new Jupyter Notebook with Python [conda env:root]*. However, it only shows the windows file system. I try to open my note book that is saved on the Linux file system using: <br>
  <code>$ jupyter lab my_linux_folder/my_notebook.ipynb</code></p>
  
  <p>Jupyter lab lunches successfully, but cannot open the notebook that is on the Linux file system and gives an error:</p>
  
  <blockquote>
    <p>Cannot open <br>
    Could not find path: /my_notebook.ipynb</p>
  </blockquote>
  
  <p>Is it possible to open a notebook that is on the Linux file system "\wsl$\" and how? <br>
  How to go to "\wsl$\" from JupyterLab file browser? <br>
  Or more generally how to open a notebook that is saved under "\wsl$\"  ? </p>
