GetDriveName Method

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.

Note:
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.

The following example illustrates the use of the GetDriveName method.

function GetDriveLetter(path)
{
   var fso, s ="";
   fso = new ActiveXObject("Scripting.FileSystemObject");
   s += fso.GetDrive(fso.GetDriveName(fso.GetAbsolutePathName(path)));
   return(s);
}

Function GetAName(DriveSpec)
   Dim fso
   Set fso = CreateObject("Scripting.FileSystemObject")
   GetAName = fso.GetDriveName(Drivespec)
End Function
