 	 * show a file picker to pick a file from

+	 * In order to pick several types of mime types they need to be passed as an
+	 * array of strings.
+	 *
+	 * When no mime type filter is given only files can be selected. In order to
+	 * be able to select both files and folders "['*', 'httpd/unix-directory']"
+	 * should be used instead.

 	 * @param title dialog title
 	 * @param callback which will be triggered when user presses Choose
 	 * @param multiselect whether it should be possible to select multiple files
