Answer:</h2>
(a) mkdir /d D:\utilities\recover
or
mkdir D:\utilities\recover
(b) rd /s D:\software\arch98
<h2>
Explanation:</h2>
(a) To make a new directory we use the md or mkdir command followed by the name of the directory as follows;
mkdir [name_of_directory]
The name of the directory could also be a relative or absolute path depending on the request.
In the task, the specified directory uses an absolute path given as D:\utilities\recover. This path is in a drive D. Therefore, if you are in another drive different than D, to run this command, it is a great idea to do that with the /d switch.
In summary:
i. if in drive D, to make a directory D:\utilities\recover, type the following command;
mkdir D:\utilities\recover
ii. if otherwise in a different drive, type the following command.
mkdir /d D:\utilities\recover
(b) To delete a directory, we use the rd or rmdir command. If the directory has contents that also need to be deleted, we use the switch /s alongside the rd or rmdir.
In the task given, the directory to be deleted is D:\software\arch98. This includes deleting all of its files too. To do this, type the following command;
rd /s D:\software\arch98
