+<div>{{APIRef("File System API")}} {{non-standard_header}}</div>
+
+<p>The <strong><code>FileSystemEntry</code></strong> interface of the File and Directory Entries API represents a single in a file system. The entry can be a file or a directory (directories are represented by the {{domxref("DirectoryEntry")}} interface). It includes methods for working with files—including copying, moving, removing, and reading files—as well as information about a file it points to—including the file name and its path from the root to the entry.</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="basic" name="basic">Basic concepts</h2>
+
+<p>You don't create <code>FileSystemEntry</code> objects directly. Instead, you will receive an object based on this interface through other APIs. This interface serves as a base class for the {{domxref("FileSystemFileEntry")}} and {{domxref("FileSystemDirectoryEntry")}} interfaces, which provide features specific to file system entries representing files and directories, respectively.</p>
+
+<p>The <code>FileSystemEntry</code> interface includes methods that you would expect for manipulating files and directories, but it also includes a convenient method for obtaining the URL of the entry: <code><a href="#toURL">toURL()</a></code>. It also introduces a new URL scheme: <code>filesystem:</code>.</p>
+
+<p>You can use the <code>filesystem:</code> scheme on Google Chrome to see all the files and folders that are stored in the origin of your app. Just use <code>filesystem:</code> scheme for the root directory of the origin of the app. For example, if your app is in <code><a href="http://www.html5rocks.com" rel="freelink">http://www.html5rocks.com</a></code>, open<code> filesystem:<a href="http://www.html5rocks.com/temporary/" rel="freelink">http://www.html5rocks.com/temporary/</a></code> in a tab. Chrome shows a read-only list of all the files and folders stored the origin of your app.</p>

+
+<p>To see an example of how <code>toURL()</code> works, see the <a href="#toURL">method description</a>. The snippet below shows you how you can remove a file by name.</p>
