Which command is used to create root directory and FAT on disk?

Solution (By Examveda Team)

Format is the command used in DOS to create the root directory and File Allocation Table (FAT) on a disk.

When you format a disk using the format command, it prepares the disk by creating the necessary file system structures, including the root directory and the FAT.
The root directory is the top-level directory of a disk, where other directories and files are stored.
The FAT is a table that DOS uses to keep track of the status of each cluster on the disk (whether it is free or allocated to a file).
The syntax for formatting a disk typically involves specifying the drive letter followed by the colon (e.g., format C: for formatting the C drive).

Chkdsk is used to check the integrity of the file system and to fix errors on a disk, but it does not create the root directory or the FAT.

Command.com is the system file that contains the DOS command interpreter, not a command used for disk formatting.

Fat is not a command in DOS; it refers to the File Allocation Table itself, not a command to create it.

Therefore, the correct answer is Option C: Format.
