These two files (nu8_d622.arj and nu8_d622.a01) are an upgrade for
Norton Utilities 8 to handle MS-DOS 6.22's online-compressing capabilities -
called 'Drivespace'.Since Microsoft was forced to cancel it's program
Doublespace they made a new program which gives MS-DOS drivespace-compression
features.The original Norton Utilities 8 couldn't handle such compressed drives
(as it couldn't handle Stacker 4-compression) so you'll need this update
if you'll - for instance - 'speedisk' your drivespace-compressed drives.
