Label (command)

label is a shell command for setting the label of a volume.
The command is supported for most variants of the FAT file system and for NTFS. It is available in various operating systems such as
DOS,
OS/2,
Windows,
ReactOS,
DR DOS 6.0,
and FreeDOS. It is available in MS-DOS versions 3.1 and later and IBM PC DOS releases 3 and later.
In modern versions of Windows, changing the label requires elevated permissions.
The current label is reported by both the dir and vol commands.
In Unix-like systems, various commands set a storage label. For instance, the command e2label is for an ext2 partition.
The command was originally designed to label floppy disks as a reminder of which one is in the disk drive. But it can be used for other types of storage media.

Use

With no options, the command accepts a single argument may start with a drive letter and may end with label text. Without a drive letter, the command operates on the volume associated with the working directory. Without label text, the command clears the label.
For example, the command line sets the label of to "Backup".
With the option, the command accepts up to two arguments: and. In this case, the argument is treated as a mount point or a volume name. If volume name is specified, the /MP option is unnecessary.
