You could wrap just this line in a Try Catch block. However, it's a
good idea to avoid using exceptions as error handlers when there are
alternatives. In particular here, do you have a reason to avoid the use
of My.Computer.FileSystem.DirectoryExists?

Dim sTableDirectory As String = Path & "\" & tbl.Name
If Not My.Computer.FileSystem.DirectoryExists(sTableDirectory) Then
My.Computer.FileSystem.CreateDirectory(sTableDirectory)
End If
