- [Voiceover] Hi, I'm Joe Marini and I'd like to welcome you to HTML5 File API In Depth. In this title, we'll see how to use the HTML5 file API to build webpages that can work with local file data, a capability that only native applications have had up until now. We'll start off with the basics. Examining how to use the HTML file input form element to allow users to select files and retrieve information about them such as their name, size, and mind type. We'll also see how to use the HTML5 file reader API to provide features like progress information, cancel-able read actions and reading just particular portions of individual files.
So if you're ready to see how the HTML5 file API can give your web apps a native flair, then let's get started with HTML5 File API in Depth.
