<p>{{APIRef("File System API")}} {{non-standard_header}}</p>
<p>La interfaz de la API <strong><code>FileSystem</code></strong> para la entrada de archivos y directorios es usada para representar un sistema de archivos. Estos objetos pueden ser obtenidos desde la propiedad {{domxref("FileSystemEntry.filesystem", "filesystem")}} en cualquier entrada del sistema de archivos . Algunos navegadores ofrecen APIs adicionales para crear y administrar el sistema de archivos , como el metodo de Chrome {{domxref("Window.requestFileSystem", "requestFileSystem()")}}.</p>
<p>This interface will not grant you access to the users filesystem. Instead you will have a "virtual drive" within the browser sandbox. If you want to gain access to the users filesystem you need to invoke the user by eg. installing a Chrome extension. The relevant Chrome API can be found <a href="https://developer.chrome.com/apps/fileSystem">here</a>.</p>
<div class="note">
<p>Because this is a non-standard API, whose specification is not currently on a standards track, it's important to keep in mind that not all browsers implement it, and those that do may implement only small portions of it. Check the {{anch("Browser compatibility")}} section for details.</p>
</div>
<h2 id="Conceptos_Basicos">Conceptos Basicos</h2>
<p>Hay dos formas de acceder a un objeto <code>FileSystem</code> :</p>
<ol>
<li>You can directly ask for one representing a sandboxed file system created just for your web app directly by calling <code>window.requestFileSystem()</code>. If that call is successful, it executes a callback handler, which receives as a parameter a <code>FileSystem</code> object describing the file system.</li>
<li>You can get it from a file system entry object, through its {{domxref("FileSystemEntry.filesystem", "filesystem")}} property.</li>
</ol>
<h2 id="Propiedades">Propiedades</h2>
<dl>
<dt>{{domxref("FileSystem.name")}} {{ReadOnlyInline}}</dt>
<dd>A {{domxref("USVString")}} representing the file system's name. This name is unique among the entire list of exposed file systems.</dd>
<dt>{{domxref("FileSystem.root")}} {{ReadOnlyInline}}</dt>
<dd>A {{domxref("FileSystemDirectoryEntry")}} object which represents the file system's root directory. Through this object, you can gain access to all files and directories in the file system.</dd>

<p>[1] Microsoft Edge implements this interface under the name <code>WebKitFileSystem</code>, and supports its use only in drag-and-drop scenarios using the {{domxref("DataTransferItem.webkitGetAsEntry()")}} method. It's not available for use in file or folder picker panels (such as when you use an {{HTMLElement("input")}} element with the {{domxref("HTMLInputElement.webkitdirectory")}} attribute.</p>
