File object provides information about -- and access to the contents of -- files. These are generally retrieved from a
object returned as a result of a user selecting files using the
input element, or from a drag and drop operation's object.
Starting in Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1)
, the File object inherits from the
interface, which provides methods and properties providing further information about the file.
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.
Fileobject as implemented by Gecko offers several non-standard methods for reading the contents of the file. These should not be used, as they will prevent your web application from being used in other browsers, as well as in future versions of Gecko, which will likely remove these methods.
