1. Why We Need to Change Home_directory:- As C:/ drive contains low space most of the time and we need to install so many plugins in Jenkins we need bigger space.
2. Wherever you want to create Home_directory Just copies all files under ./jenkins folder from this path C:/users/User_Name/.Jenkins

5. Restart the server and Jenkins
