The initial 1982 release supported DOS 1.x and featured the UNERASE utility. This allowed files to be undeleted by restoring the first letter of the directory entry (a feature of the FAT file system used in MS-DOS, albeit one that was not originally documented). 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.' ġ4 programs were included, on three floppy disks, list price $80: #Norton disk doctor vista software#

The PRINT program was renamed LPRINT to avoid conflict with the DOS command introduced in MS-DOS 2.0 as PRINT.COM. This version, released in 1984, included Directory Sort, Disk Test, File Attributes, File Find, File Size, Line Print, List Directories, System Information, Text Search, Volume Label, Wipe Disk and Wipe File. This 1986 version added the Quick UnErase (QU) and Unremove Directory (UD) programs.

Norton Utilities 6.0 supports DOS 5 and Windows 3.1. It includes Windows Program Manager support, but the tools are still DOS-based, so a set of icons were supplied. It includes Norton Disk Doctor, Disk Editor, Disk Tools, Speed Disk, Norton Cache, Disk Monitor, Diskreet, NDisk, System Information, NDOS. The speed of Speed Disk was faster than previous release.ĭiskreet supports Data Encryption Standard. System Information now includes more detailed information on installed system. UnErase takes advantage of DOS 5.0's Delete Tracking and Mirror File features to recover data. However, MS-DOS 5.0 added a new UNDELETE.exe program, licensed from Norton competitor Central Point Software, which took advantage of the same Delete Sentry control and Deletion-tracking files. (The DOS ERASE command is the same as the DEL (Delete) command.) Windows 95's Recycle Bin soon further reduced the value of UnErase. It supports MS-DOS 6.0, DoubleSpace, Stacker, and SuperStor disk compression tools. It includes Norton Disk Doctor, Disk Editor, Undelete, SmartCan, NDOS, System Information, File Find, Norton Change Directory. Speed Disk remained as well, although SPEEDISK.exe was licensed by Microsoft and incorporated into MS-DOS as DEFRAG.exe in MS-DOS 6 onward. Release 7.0 had revised user interfaces for the utilities that feature a menu-driven user interface.

Also some of these tools now did not need to run in full-screen-mode but just displayed a window in the center of the screen, like the disk formatter or the disk duplicator utility.ĭisk Editor now includes Advanced Recovery Mode. Windows utilities include Norton Disk Doctor, Speed Disk, System Watch, File Compare, INI Tracker, INI Tuner, INI editor, INI Advisor Norton Utilities for Windows 95 and later Release 8.0 was nearly the same as 7.0, but added Windows 3.1 utilities.ĭOS Utilities include Norton Disk Doctor, System Information, Change Directory, FileFind, Diskreet, DUPDISK, File Fix, NDOS, Batch Enhancer, Norton Integrator, Speed Disk.
