On MS-DOS, the command is available in versions 2 and later.^[8] Paragon Technology Systems PTS-DOS 2000 Pro also includes a vol implementation.^[9]

vol [Drive:]

Arguments:

Drive: This command-line argument specifies the drive letter of the disk for which to display the volume label and serial number.

Note:

On Windows, the volume serial number is displayed only for disks formatted with MS-DOS version 4.0 or later.
OS/2 allows the user to specify more than one drive. The vol command displays the volume labels consecutively.

[C:\]vol C:

The volume label in drive C is OS/2.
The Volume Serial Number is 0815:1611.

C:\Users\root>vol C:
Volume in drive C is Windows
Volume Serial Number is 080F-100B

In the example above, if drive C: has no volume label, "has no label" is shown instead of "is Windows".
