The default directory of Jupyter notebook is the C:\Users\User Name\
I want to open several Jupyter notebooks in different folders at the same time (some of them in portable drives). additionally, I want to run Jupyter under specific Anaconda environment, with specific libraries and version of python.
I tried until I found the easiest and fastest solution for Windows which I will post in the answers below for the benefit of others.
I have provided the solution for windows, so I hope that others can add similar solutions for Mac and Linux.
Thanks
