The correct answer is: A. Show all details of file
The dir command is used to list the files and folders in a directory. The /w switch tells dir to list the files in wide format, which means that it will show more information about each file, such as the file size and date modified.
Here is an example of the output of the dir /w command:
“`
Volume in drive C is OS
Volume Serial Number is 1234-5678
Directory of C:\
07/26/2023 09:23 AM
07/26/2023 09:23 AM
07/26/2023 09:23 AM 10 File(s) 0 bytes
2 Dir(s) 1024000000 bytes free
“`
As you can see, the dir /w command shows the file name, size, and date modified for each file.
Option B is incorrect because the dir /w command does not only show the file name and directory name. It also shows the file size and date modified.
Option C is incorrect because the dir /w command does not only show the directory. It also shows the files in the directory.
Option D is incorrect because the dir /w command does not show all of the above. It only shows the file name, size, and date modified for each file.
