- [Instructor] Now that we have…a good grasp of reading files from the file system,…let's move on to trying to read directories…with the file system as well.…Let's create a new demo file.…And once again, we'll need access to the file system.…And so I'll require an fs.…And we'll use a function from…the file system called readdir.…The first parameter we'll need…to pass in is the location we want…to read our directories from.…
So let's use Drive C as an example.…Then once again, we'll create a callback…that takes in an error and data.…And then let's console-log the data.…Let's save that, and I'll use nodemon to run demo.…And you can see we're getting all…of the directories inside our Drive C.…As you can see, reading directories is very straightforward.…
Next let's take a look at writing files.…
