File and Directory Entries API

First of all this directory contains the implementation of the Entries API. This API consists of types to expose read-only access to file and directory entries to the web, primarily used by drag-and-drop and <input type=file>. Our implementation doesn't match the interface names of the spec, but otherwise should be pretty close to the spec.

File API: Directories and FileSystem

Secondly this directory contains the implementation of something similar to the deprecated w3c file-system-api. This API is very similar to the previous Entries API, but it also adds support for writing and modifying to files and directories, as well as a way to get access to a origin scoped sandboxed filesystem.
