To write a volume label on a floppy or a hard disk, a Windows-based application can use the C run-time function _dos_create(). However, if the disk already has a volume label, _dos_create() fails unless the old label is first deleted.

SETVOL is a sample in the Microsoft Software Library that demonstrates writing a volume label to the disk in drive A. SETVOL makes use of the Extended File Control Block Structure and uses some in-line assembly to check whether a volume label exists. If so, SETVOL deletes the label.
