<class name="QFSFileEngine" doc="/**
&lt;p&gt;The &lt;a href=&quot;QFSFileEngine.html#QFSFileEngine(java.lang.String)&quot;&gt;&lt;tt&gt;QFSFileEngine&lt;/tt&gt;&lt;/a&gt; class implements Qt's default file engine.&lt;/p&gt;
&lt;p&gt;This class is part of the file engine framework in Qt. If you only want to access files or directories, use &lt;a href=&quot;QFile.html&quot;&gt;&lt;tt&gt;QFile&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;QFileInfo.html&quot;&gt;&lt;tt&gt;QFileInfo&lt;/tt&gt;&lt;/a&gt; or &lt;a href=&quot;QDir.html&quot;&gt;&lt;tt&gt;QDir&lt;/tt&gt;&lt;/a&gt; instead.&lt;/p&gt;
&lt;p&gt;&lt;a href=&quot;QFSFileEngine.html#QFSFileEngine(java.lang.String)&quot;&gt;&lt;tt&gt;QFSFileEngine&lt;/tt&gt;&lt;/a&gt; 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 &lt;a href=&quot;QAbstractFileEngine.html#QAbstractFileEngine()&quot;&gt;&lt;tt&gt;QAbstractFileEngine&lt;/tt&gt;&lt;/a&gt; subclass. To install your custom file engine, you must also subclass &lt;a href=&quot;QAbstractFileEngineHandler.html&quot;&gt;&lt;tt&gt;QAbstractFileEngineHandler&lt;/tt&gt;&lt;/a&gt; and create an instance of your handler.&lt;/p&gt;
&lt;p&gt;It can also be useful to create a &lt;a href=&quot;QFSFileEngine.html#QFSFileEngine(java.lang.String)&quot;&gt;&lt;tt&gt;QFSFileEngine&lt;/tt&gt;&lt;/a&gt; object directly if you need to use the local file system inside QAbstractFileEngine::create(), in order to avoid recursion (as higher-level classes tend to call QAbstractFileEngine::create()).&lt;/p&gt;
