+    \qmlclass FolderListModel
+    \brief The FolderListModel provides a model of the contents of a folder in a filesystem.
+
+    FolderListModel provides access to the local filesystem.  The \e folder property
+    specifies the folder to list.
+
+    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.
+
+    The roles available are:
+    \list
+    \o fileName
+    \o filePath
+    \endlist
+
+    Additionally a file entry can be differentiated from a folder entry
+    via the \l isFolder() method.
