I suppose you are using Windows system.
Once you open CMD you would be shown with the default location i.e. like this
C:\Users\Admin - In your case its admin as mentioned else it will be the username of your computer
Consider if you want to move to E directory then simply type E:
This will move the user to E: Directory. Now change to what ever folder you want to point to in E: Drive
Ex: If you want to move to Software directory of E folder then first type
E:
then type the location of the folder
cd E:\Software
