&lt;p&gt;The &lt;a href=&quot;QAbstractFileEngine.html#QAbstractFileEngine()&quot;&gt;&lt;tt&gt;QAbstractFileEngine&lt;/tt&gt;&lt;/a&gt; class provides an abstraction for accessing the filesystem.&lt;/p&gt;
&lt;p&gt;The &lt;a href=&quot;QDir.html&quot;&gt;&lt;tt&gt;QDir&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;QFile.html&quot;&gt;&lt;tt&gt;QFile&lt;/tt&gt;&lt;/a&gt;, and &lt;a href=&quot;QFileInfo.html&quot;&gt;&lt;tt&gt;QFileInfo&lt;/tt&gt;&lt;/a&gt; classes all make use of a &lt;a href=&quot;QAbstractFileEngine.html#QAbstractFileEngine()&quot;&gt;&lt;tt&gt;QAbstractFileEngine&lt;/tt&gt;&lt;/a&gt; internally. If you create your own &lt;a href=&quot;QAbstractFileEngine.html#QAbstractFileEngine()&quot;&gt;&lt;tt&gt;QAbstractFileEngine&lt;/tt&gt;&lt;/a&gt; subclass (and register it with Qt by creating a &lt;a href=&quot;QAbstractFileEngineHandler.html&quot;&gt;&lt;tt&gt;QAbstractFileEngineHandler&lt;/tt&gt;&lt;/a&gt; subclass), your file engine will be used when the path is one that your file engine handles.&lt;/p&gt;
&lt;p&gt;A &lt;a href=&quot;QAbstractFileEngine.html#QAbstractFileEngine()&quot;&gt;&lt;tt&gt;QAbstractFileEngine&lt;/tt&gt;&lt;/a&gt; refers to one file or one directory. If the referent is a file, the &lt;a href=&quot;QAbstractFileEngine.html#setFileName(java.lang.String)&quot;&gt;&lt;tt&gt;setFileName&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;QAbstractFileEngine.html#rename(java.lang.String)&quot;&gt;&lt;tt&gt;rename&lt;/tt&gt;&lt;/a&gt;, and &lt;a href=&quot;QAbstractFileEngine.html#remove()&quot;&gt;&lt;tt&gt;remove&lt;/tt&gt;&lt;/a&gt; functions are applicable. If the referent is a directory the &lt;a href=&quot;QAbstractFileEngine.html#mkdir(java.lang.String, boolean)&quot;&gt;&lt;tt&gt;mkdir&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;QAbstractFileEngine.html#rmdir(java.lang.String, boolean)&quot;&gt;&lt;tt&gt;rmdir&lt;/tt&gt;&lt;/a&gt;, and &lt;a href=&quot;QAbstractFileEngine.html#entryList(com.trolltech.qt.core.QDir.Filters, java.util.List&lt;java.lang.String&gt;)&quot;&gt;&lt;tt&gt;entryList&lt;/tt&gt;&lt;/a&gt; functions are applicable.

&lt;p&gt;A &lt;a href=&quot;QAbstractFileEngine.html#QAbstractFileEngine()&quot;&gt;&lt;tt&gt;QAbstractFileEngine&lt;/tt&gt;&lt;/a&gt; subclass can be created to do synchronous network I/O based file system operations, local file system operations, or to operate as a resource system to access file based resources.&lt;/p&gt;
