-    \qmlmodule Qt.labs.folderlistmodel 2.\QtMinorVersion

-    \ingroup qmlmodules
-    \brief The FolderListModel provides a model of the contents of a file system folder.
-
-    To use this module, import the module with the following line:
-
-    \qml
-    import Qt.labs.folderlistmodel
-    \endqml
-*/
-
-/*!
-    \qmltype FolderListModel
-    \inqmlmodule Qt.labs.folderlistmodel
-    \instantiates QQuickFolderListModel
-    \ingroup qtquick-models
-    \brief The FolderListModel provides a model of the contents of a file system folder.
-
-    FolderListModel provides access to information about the contents of a folder
-    in the local file system, exposing a list of files to views and other data components.
-
-    \note This type is made available by importing the \c Qt.labs.folderlistmodel module.
-    \e{Elements in the Qt.labs module are not guaranteed to remain compatible
-    in future versions.}
-
-    \qml
-    import Qt.labs.folderlistmodel
-    \endqml
-
-    The \l folder property specifies the folder to access. Information about the
-    files and directories in the folder is supplied via the model's interface.
-    Components access names and paths via the following roles:
-
-    \list
-    \li \c fileName
-    \li \c filePath
-    \li \c fileURL (since Qt 5.2; deprecated since Qt 5.15)
-    \li \c fileUrl (since Qt 5.15)
-    \li \c fileBaseName
-    \li \c fileSuffix
-    \li \c fileSize
-    \li \c fileModified
-    \li \c fileAccessed
-    \li \c fileIsDir
-    \endlist
-
-    Additionally a file entry can be differentiated from a folder entry via the
-    isFolder() method.
-
-    \section1 Filtering
-
-    Various properties can be set to filter the number of files and directories
-    exposed by the model.
-
-    The \l nameFilters property can be set to contain a list of wildcard filters
-    that are applied to names of files and directories, causing only those that
-    match the filters to be exposed.
-
-    Directories can be included or excluded using the \l showDirs property,
-    navigation directories can also be excluded by setting the \l showDotAndDotDot
-    property to false, hidden files can be included or excluded using the
-    \l showHidden property.
-
-    It is sometimes useful to limit the files and directories exposed to those
-    that the user can access. The \l showOnlyReadable property can be set to
-    enable this feature.
-
-    \section1 Example Usage
-
-    The following example shows a FolderListModel being used to provide a list
-    of QML files in a \l ListView:
-
-    \qml
-    import QtQuick
-    import Qt.labs.folderlistmodel
-
-    ListView {
-        width: 200; height: 400
-
-        FolderListModel {
-            id: folderModel
-            nameFilters: ["*.qml"]
-        }
-
-        Component {
-            id: fileDelegate
-            Text { text: fileName }
-        }
-
-        model: folderModel
-        delegate: fileDelegate
-    }
-    \endqml
-
-    \section1 Path Separators
-
-    Qt uses "/" as a universal directory separator in the same way that "/" is
-    used as a path separator in URLs. If you always use "/" as a directory
-    separator, Qt will translate your paths to conform to the underlying
-    operating system.
