+ * and suffer undesirable consequences. The details of what is

+ *
+ * In future, we will likely support filtering based on filename extensions
+ * (for example, aFilters could be "*.jpg; *.jpeg; *.gif"), but that isn't
+ * supported yet. Once supported, files that don't match a specified
+ * extension (if any are specified) would be filtered out. This
+ * functionality would allow us to apply the 'accept' attribute from
+ * <input type=file directory accept="..."> to the results of a directory
