How do I make a file system?

I'm making a little "operating system" that runs inside Construct 3, and I want to know if I can store persistent files within the project that can be read and written to, also with the ability to import, create, and delete files. Is this possible? If so, how?

Look at the local storage plug-in. That’s persistent storage. It’s also possible to interact with a server to store files there. But that’s probably overkill. Also if you use desktop export you can actually read and write files.
