Does it support streaming for large files?

Yes, it provides both 'stream' for reading and 'sink' for writing, enabling efficient handling of large files without exhausting system memory.

What are scoped temporary directories?

These are temporary folders created within an Effect scope that are automatically deleted when the scope finishes, ensuring no leftover files remain on the system.

Can I watch file changes in real-time?

Yes, it includes a watch method that returns a Stream of FileSystem.WatchEvent, allowing you to react to file and directory changes dynamically.

How does it handle file system errors?

It uses the Effect error channel with PlatformError and SystemErrorReason, providing specific codes like NotFound, PermissionDenied, and AlreadyExists for precise recovery.

Does this work in the browser?

Yes, the Effect FileSystem abstraction is designed to work across Node.js, Bun, and browser environments seamlessly.
