The volume label is displayed as part of a directory listing, as well as the volume serial number, if one exists.
The Label command is invoked in the CMD processor. It has the following syntax:
LABEL \[/MP\] \[volume\] \[label\]
If LABEL is used without any parameters, you can interactively change or delete the existing label of the current drive.
NOTE: If you specify a volume name, the /MP switch is NOT required.
