GetExtensionName Method 

Returns a string containing the extension name for the last component in a path.

object.GetExtensionName(path) 

Arguments

• 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);

}

Function GetAnExtension(DriveSpec)

   Dim fso

   Set fso = CreateObject("Scripting.FileSystemObject")

   GetAnExtension = fso.GetExtensionName(Drivespec)

End Function

Applies To:

FileSystemObject Object
