87/*! \class QFSFileEngine-
88 \inmodule QtCore-
89 \brief The QFSFileEngine class implements Qt's default file engine.-
90 \since 4.1-
91 \internal-
92-
93 This class is part of the file engine framework in Qt. If you only want to-
94 access files or directories, use QFile, QFileInfo or QDir instead.-
95-
96 QFSFileEngine is the default file engine for accessing regular files. It-
97 is provided for convenience; by subclassing this class, you can alter its-
98 behavior slightly, without having to write a complete QAbstractFileEngine-
99 subclass. To install your custom file engine, you must also subclass-
100 QAbstractFileEngineHandler and create an instance of your handler.-
101-
102 It can also be useful to create a QFSFileEngine object directly if you-
103 need to use the local file system inside QAbstractFileEngine::create(), in-
104 order to avoid recursion (as higher-level classes tend to call-
105 QAbstractFileEngine::create()).-
