It's the "File System Access API," the one that allows the browser to read/write files on your actual computer. It's an I/O feature, impossible to polyfill.

The similarly named "FileSystem API" gives you access to a sandboxed "virtual drive" in the browser. Firefox has supported that for years, and polyfills are possible, but it's irrelevant in this case.

I believe it still counts as a polyfill, even if it doesn't do what it says on the can (but it has compatible interface, so your app runs).
