Changes

Firstly in In the Dos window, you'll see note that I'm running Windows 10. You'll see the first command of "cd \" which brings me back to the root of the directory.

I then issue the "dir *" and I get a listing of the files. Directories have <DIR> in their title. Files, you can see the size in bytes. You'll see file names and the extensions as well. , however you'll note the folder name Program Files. How can it have a space in it. ? Lets try some commands.

I then go back to root and try cd "Program Files", with the file name in double inverted commas , and that works. Using the double inverted commas was used in Windows XP , and other versions of Windows to facilitate spaces in the folder name.
