Using the HTML5 Filesystem API

Several client-side storage options are available to web applications, but one area that's been lacking until now is file I/O—the ability to organize binary data into a true hierarchy of folders. That has changed with the advent of HTML5. With this book, you'll learn how to provide your applications with a file system that enables them to create, read, and write files and folders in a sandboxed section of the user's local filesystem.

Author Eric Bidelman, a Senior Developer Programs Engineer on the Google Chrome team, provides several techniques and complete code examples for working with the HTML5 Filesystem API.
