The Metadata
interface is used by the File and Directory Entries API to contain information about a file system entry. This metadata includes the file's size and modification date and time.
Note: This interface isn't available through the global scope; instead, you obtain a Metadata

using the method FileSystemEntry.getMetadata()
.
