ELI5:How can a file that is 0 bytes can be stored when technically it shouldn't exist because it contains no data?

Think of it as a filing cabinet.  You open the drawer and you pull out a folder.  The folder has nothing at all in it.  It is a file with no data.  If someone were to ask you how big the file is you would say it had no data.  Even though it has no data, there's still a folder there and it still takes up space in the filing cabinet albeit not nearly as much as the file with a hundred pages in it.
