Description
Returns a string containing the extension name for the last component in a path.
Syntax
object.GetExtensionName(path)

The GetExtensionName method syntax has these parts:

Part Description
object Required. Always the name of a FileSystemObject.
path Required. The path specification for the component whose extension name is to be returned.

Remarks
For network drives, the root directory (\) is considered to be a component.

The GetExtensionName method returns a zero-length string ("") if no component matches the path argument.

The following example illustrates the use of the GetExtensionName method:

function ShowExtensionName(filespec)
{
  var fso, s = "";
  fso = new ActiveXObject("Scripting.FileSystemObject");
  s += fso.GetExtensionName(filespec);
  return(s);
}
