While working with MS-DOS, which command is used to restore files that were backed up using the BACKUP command? A. COPY B. DISKCOPY C. RESTORE D. STORE E. None of the above

The correct answer is C. RESTORE.

The BACKUP command creates a backup of files on a disk. The RESTORE command restores files from a backup created with the BACKUP command.

The COPY command copies files from one disk to another. The DISKCOPY command copies the contents of one disk to another disk. The STORE command is not a valid MS-DOS command.

Here is an example of how to use the RESTORE command to restore a file named “myfile.txt” from a backup file named “mybackup.bkf”:

restore mybackup.bkf myfile.txt

This command will restore the file “myfile.txt” from the backup file “mybackup.bkf” to the current directory.
