To create workspace directory on Windows

Hello I would like to know how I can create a workspace directory on Windows. I have installed Python 3.8 and have been trying to put the following function on it
$ export ML_PATH="$HOME/ml" and
$ mkdir -p $ML_PATH

but both of them are not working. I have tried the same on windows command prompt but still an error.
Do I need to create this directory through GitHub prompt or by Anaconda prompt. I have installed both of them.

Secondly, how I can install virtualenv through Anaconda?

Lastly, when I am trying to upload the raw data of housing on Jupyter it shows error after
housing = load_housing_data()
housing.head()
I will be looking forward to your advice.

Kind regards,
Nishant
