MDN wants to learn about developers like you:

This API is available on Firefox OS for privileged or certified applications only.


The get method is used to retrieve a read-only file from a given storage area.

If the request is successful, the request's result is a File object containing the data of the original file on the device.


var instanceOfDOMRequest = instanceOfDeviceStorage.get(fileName);


A string representing the full name (path + file name) of the file to retrieve.


It returns a DOMRequest object to handle the success or error of the operation.


var sdcard = navigator.getDeviceStorage("sdcard");

var request = sdcard.get("myFile.txt");

request.onsuccess = function () {
  var name =;
  console.log('File "' + name + '" successfully retrieved from the sdcard storage area');

request.onerror = function () {
  console.warn('Unable to get the file: ' + this.error);


Not part of any specification.
