While working with MS-DOS, which command is used to display a list of deleted files that DOS can undelete? A. UNDELETE *.* B. UNDELETE/ALL C. UNDELETE/LIST D. UNDELETE E. None of the above

The correct answer is C. UNDELETE/LIST.

The UNDELETE command is used to undelete files that have been deleted from a disk. The UNDELETE/LIST command displays a list of all the deleted files that can be undeleted.

The UNDELETE command can be used with the following options:

• /ALL: Undeletes all deleted files.
• /LIST: Displays a list of all the deleted files that can be undeleted.
• /UNDELETE: Undeletes the specified file.

The UNDELETE command is not available in all versions of MS-DOS. In versions of MS-DOS that do not have the UNDELETE command, you can use the DOS 6.22 or later RESTORE command to undelete files.

The RESTORE command can be used with the following options:

• /ALL: Restores all deleted files.
• /LIST: Displays a list of all the deleted files that can be restored.
• /RESTORE: Restores the specified file.

The RESTORE command is available in all versions of MS-DOS.
