Drive Volume Labels; What are they and Why change them

Drive volume labels are used by various programs to track the location of data.  Visionary uses the drive volume label to allow the use of optical disks and external hard drives.  Because of that, the labels need to be unique on the computer.

An easy reason to understand why drive volume labels are needed is the use of an optical drive (cd/dvd).  The drive letter will always be d:\ (or whatever on your computer); but the disk in the drive can be changing regularly.  Visionary needs to know what disk is available; for instance for video playback.  (Whenever a cd/dvd is "burned" an optional electronic label is included.)

(As an aside, all network shared drives already have a drive volume label.  In the case of these shares, the actual share name is the label.)

Adding a drive volume label to a drive will not affect anything on the computer.  If the drive is not already labeled, adding a label cannot affect anything.  If it already has a label, there is no need to change it.  The addition of a drive volume label does not change the drive letter, that remains the same.

To check to see if your drives are already labeled, use Windows Explorer, My Computer or File Explorer (your available choices are dependent on the version of Windows that is being used.)

When your favorite file tool is open, right-click on your c:\ drive and choose Rename.  If it currently says "Local Drive", it means there is no drive volume label assigned.  In that case, give it a name.  We suggest something like "CDrive".  The name doesn't really matter except that it should not be a duplicate.  For instance, naming all your external drives "Data" and connecting them all at once is going to cause problems.
