This directory contains the implementation of the new and still under development Native File System API.

It consists of the following parts:

• FileSystemHandle, FileSystemFileHandle and FileSystemDirectoryHandle: these interfaces mimic the old Entry interfaces, but expose a more modern promisified API.

• getSystemDirectory: An entry point (exposed via FileSystemDirectoryHandle) that today only gives access to the same sandboxed filesystem as what was available through the old API. In the future this could get extended to add support for other directories as well.

• FileSystemWriter: a more modern API with similar functionality to the old FileWriter API. The implementation of this actually does make use of a different mojom interface than the old API. But since the functionality is mostly the same, hopefully we will be able to migrate the old implementation to the new mojom API as well.

• chooseFileSystemEntries: An entry point, currently on window, that lets a website pop-up a file picker, prompting the user to select one or more files or directories, to which the website than gets access.
