         URL schemes include http, ftp, s3, and file. For file URLs, a host is
         expected. A local file could be:
         ``file://localhost/path/to/table.parquet``.
+        A file URL can also be a path to a directory that contains multiple

         If you want to pass in a path object, pandas accepts any
