Window Command Prompt

Can you please show how to enter these commands into the computer. I mostly do not understand #2, adding Dir_2 to Dir_1.

1) Create a folder named Dir_1 in any place of your liking. 2) Create another folder named Dir_2 inside Dir_1 folder. 3) Inside Dir_1 folder, create a file named file_1.txt and type the contents "CIT168 is hard but fun!" in the file. 4) Copy file1_.txt file to Dir_2 folder 5) Display the contents of file_1.txt file from Dir_2 folder. You cannot use notepad to display the contents. Use appropriate command to display the contents on command(s) prompt itself.
