1. Use the dir command to list the contents of the root directory on the h: drive or any other drive drive except c: drive
    h:\> dir
 
2.    Invoke the MS-DOS full screen text editor utility EDIT to create a text file called hello.txt. Follow the instructions given on the screen. The "Survival Guide" gives instructions for using EDIT.
    h:\> edit hello.txt

Enter the line

    Hello World!

Use File|Save and File|Exit to save your work and to quit EDIT
3.    Use the type command to display contents of hello.txt
    h:\> type hello.txt
You should see
    Hello World!

4.    Use the md command to create (make) a new directory called mydir
    h:\> md mydir
5.   Use the cdcommand to change the default directory to mydir
 
    h:\> cd mydir

6.    Use dir to display the contents of mydir. It should contain no files except for "pointers" to itself and it's parent.
    h:\mydir> dir

7.    Use the copy command to copy the file hello.tx in the root directory to mydir. The target name defaults to hello.txt
    h:\mydir> copy h:\hello.txt

8.    Use dir to display the contents of mydir. You should see hello.txt listed.
    h:\mydir> dir

9.    Use md to create (make) a subdirectory for mydir called mysubdir.
    h:\mydir> md mysubdir

10.    Use cd to change the default directory to mysubdir
    h:\mydir> cd mysubdir

11.    Copy hello.txt to mysubdir. Use the mydir directory copy of hello.txt
    h:\mydir\mysubdir> copy h:\mydir\hello.txt

Alternately use ..  (two dots) to refer to mysubdir parent directory
    h:\mydir\mysubdir> copy ..\hello.txt

12.    Make a second copy of hello.txt but call it hello1.txt
    h:\mydir\mysubdir> copy h:\hello.txt hello1.txt

13.    Use the ren command to rename hello.txt as hello2.txt
    h:\mydir\mysubdir> rename hello.txt hello2.txt

14.    Check your work - display the contents of mysubdir. You should see two files : hello1.txt and hello2.txt
    h:\mydir\mysubdir> dir

15.    Check that the contents of hello2.txt has not changed by displaying it.
    h:\mydir\mysubdir> type hello2.txt

16    Using a wildcard delete all files in mysubdir. Be careful. Using wildcards in dangerous so hit N to cancel the command!
    h:\mydir\mysubdir> del *.*
Instead use a wild card to delete all files with a .txt extension
    h:\mydir\mysubdir> del *.txt 

Use the dir command to check that both files are gone
    h:\mydir\mysubdir> dir
17.    Return to the mydir directory
    h:\mydir\mysubdir> cd \mydir
Alternately you could have typed cd ..

18.    Use the dir command to view the contents of the mydir directory.
    h:\mydir> dir

19.    Use the rd command to remove the mysubdir directory.
    h:\mydir> rd mysubdir

20.    Use the dir command to check that the mysubdir subdirectory is gone
    h:\mydir> dir

21.    Return to the root directory
    h:\mydir> cd \

22.    Delete the mydir copy of hello.txt
    h:\> del \mydir\hello.txt
Then check that it's gone
    h:\> dir mydir
But the root copy of hello.txt is still there
    h:\> dir

23.    Remove the mydir from the root directory
    h:\> rd mydir

24.    And delete hello.txt from the root directory
    h:\> del hello.txt
