Editing Norton Utilities (section)

==Norton Utilities for DOS and Windows 3.1==
===Version 1.0===
The initial 1982 release supports DOS 1.x and features the UNERASE utility. This allows files to be [[undeletion|undeleted]] by restoring the first letter of the directory entry (a workaround of the [[FAT file system]] used in [[DOS]]). The UNERASE utility was what launched NU on its path to success. Quoting Peter Norton, "Why did The Norton Utilities become such popular software? Well, industry wisdom has it that software becomes standard either by providing superior capabilities or by solving problems that were previously unsolvable. In 1982, when I sat down at my PC to write Unerase, I was solving a common problem to which there was no readily available solution."<ref name="Krumm_1990"/>

14 programs are included, on three [[floppy disk]]s, list price $80:<ref name="Norton_1983"/><ref name="Ad_1982"/>

The executable files were [[file compression|compressed]] with Realia's Spacemaker.<ref name="Parsons_2019_NU"/><ref name="Necasek_2019_NU"/>

It also includes a licensed version of the [[4DOS]] replacement for [[COMMAND.COM]] called [[4DOS#NDOS|NDOS]].  This version also allows the choice of "classic" names (such as FF.EXE) or longer names (such as FINDFAST.EXE); these are configurable in the updated version of the Norton Integrator menu system.

The speed of Speed Disk is improved over the previous release.

Diskreet supports [[Data Encryption Standard]].

System Information now includes more detailed information on installed system.

UnErase takes advantage of [[MS-DOS#MS-DOS_5.x|DOS 5.0]]'s Delete Tracking and Mirror File features to recover data.<ref>''InfoWorld'', 1991-06-10, p. 117</ref>  However, MS-DOS 5.0 adds a new <code>UNDELETE.exe</code> program, licensed from Norton competitor [[Central Point Software]],<ref>Upon executing the UNDELETE command in [[MS-DOS#MS-DOS_6.x|MS-DOS 6.22]], the message: "UNDELETE - A delete protection facility Copyright (C) 1987-1993 Central Point Software, Inc." is displayed.</ref> which takes advantage of the same Delete Sentry control and Deletion-tracking files. (The ERASE command is an alias for the DEL (Delete) command in the DOS [[command-line interpreter|command line]]). [[Windows 95]]'s [[Recycle Bin (Windows)|Recycle Bin]] soon further reduced the need for UnErase.

===Version 7.0===
Release 7.0 supports MS-DOS 6.0, [[DoubleSpace]], [[Stac Electronics|Stacker]] and [[SuperStor]] disk compression tools.

Tools includes Norton Disk Doctor, Disk Editor, Undelete, SmartCan, [[4DOS#NDOS|NDOS]], System Information, File Find, Norton Change Directory.<ref>{{cite web |url=http://www.atarimagazines.com/compute/issue158/132_The_Norton_Utilities.php |title=The Norton Utilities 7.0 |author-first=Clifton |author-last=Karnes |work=Atari Magazine}}</ref>

Speed Disk remains as well, although <code>SPEEDISK.exe</code> was licensed by [[Microsoft]] and incorporated into [[MS-DOS]] as <code>DEFRAG.exe</code> in MS-DOS 6.0 onward.<ref>Upon executing the DEFRAG command in MS-DOS 6.22, the message: "Microsoft Defrag for MS-DOS Copyright 1988-1993 Symantec Corporation" is displayed. "About MS-DOS Defragmenter" also states, "Technology from the Norton Utilities"</ref>

Release 7.0 has revised user interfaces for the utilities that feature a menu-driven user interface.  Also some of these tools now do not need to run in full-screen-mode but just display a window in the center of the screen, like the disk formatter or the disk duplicator utility.

Disk Editor now includes Advanced Recovery Mode.
