<p>File objects may be obtained from a {{domxref("FileList")}} object returned as a result of a user selecting files using the {{HTMLElement("input")}} element, from a drag and drop operation's {{domxref("DataTransfer")}} object, or from the <code>mozGetAsFile()</code> API on an {{domxref("HTMLCanvasElement")}}.</p>

<p>Important note: <code>FileReader</code> is used to read file content from the user's (remote) system in secure ways only. It cannot be used to read a file by pathname from a file system. To read files by pathname in JavaScript, standard Ajax solutions should be used to do server-side file reading, with CORS permission if reading cross-domain.</p>
