class File extends Blob
The File interface provides information about -- and access to the contents of -- files.
These are generally retrieved from a FileList object returned as a result of a user selecting files using the input element, or from a drag and drop operation's DataTransfer object.
The file reference can be saved when the form is submitted while the user is offline, so that the data can be retrieved and uploaded when the Internet connection is restored.
