<h2>Detailed Description</h2>
<p>The QFSFileEngine class implements Qt's default file engine.</p>
<p>This class is part of the file engine framework in Qt. If you only want to access files or directories, use <a href="qfile.html">QFile</a>, <a href="qfileinfo.html">QFileInfo</a> or <a href="qdir.html">QDir</a> instead.</p>
<p>QFSFileEngine is the default file engine for accessing regular files. It is provided for convenience; by subclassing this class, you can alter its behavior slightly, without having to write a complete <a href="qabstractfileengine.html">QAbstractFileEngine</a> subclass. To install your custom file engine, you must also subclass <a href="qabstractfileenginehandler.html">QAbstractFileEngineHandler</a> and create an instance of your handler.</p>
<p>It can also be useful to create a QFSFileEngine object directly if you need to use the local file system inside <a href="qabstractfileengine.html#create">QAbstractFileEngine::create</a>(), in order to avoid recursion (as higher-level classes tend to call <a href="qabstractfileengine.html#create">QAbstractFileEngine::create</a>()).</p>
