Returns a string containing the name of the drive for a specified path.
The GetDriveName method syntax has these parts:
|object||Required. Always the name of a FileSystemObject.|
|path||Required. The path specification for the component whose drive name is to be returned.|
The GetDriveName method returns a zero-length string ("") if the drive can't be determined.
The GetDriveName method works only on the provided path string. It does not attempt to resolve the path, nor does it check for the existence of the specified path.
