Summary

The File API allows a developer to use javascript to access the contents and local path of the file uploaded from the input file widget. This enables the developer to build a javascript frontend that allows the website to show a preview of the file uploaded. By using the File API, the developer can also enable a user to upload files via drag-and-drop. Prior to the File API, functionalities like these can only be accomplished via Flash or other plugins.
