File Attributes

The java.io and the extended file system APIs support a limited set of file attributes that are considered common across many file system types. For instance all file systems are assumed to support some notion of file size, modification time, access control for read or write and filetypes with common behaviors like directories and "flat" files. The NFS protocol supports some file attributes that are not in the "common" set like the file owner and group (UID and GID), creation time, last access time, and UNIX(TM)-style permission bits. While these attributes are not accessible through the API they will be available through the XFileExtensionAccessor in a subsequent release of the NFS classes.
