Ersatz für With Application.FileSearch in Excel 2010

Hallo,

habe in einer Excel Mappe folgendes VBA Script:

Private Function isFileAvailable(filename As String) As Boolean
With Application.FileSearch
.NewSearch
.filename = Right(filename, Len(filename) - InStrRev(filename, "\"))
.LookIn = Left(filename, InStrRev(filename, "\"))
isFileAvailable = .Execute() > 0
End With

End Function

In Excel 2010 funktioniert leider "With Application.FileSearch" nicht mehr.

Kennt jemand eine Alternative?

Gruß
Yvonne

Function isFileAvailable(filename As String) As Boolean
isFileAvailable = CreateObject("Scripting.FileSystemObject").FileExists(filename)  
End Function
