how to get full file name

here is my question:

how do you get full file name if you have spaces in the file name ex:  Bottom laser.sldprt

here is my code

I know that the red number is where the macro reads but how can I get full name (without sheet number in a drawing file)

If ("" = Rev) Then
       
            ModName = Split(swModel.GetTitle, ".")(0)
            'ModName = Left(swModel.GetTitle, InStrRev(swModel.GetTitle, ".") - 1)
        Else
       
            ModName = Split(swModel.GetTitle)(0) & " REV" + Rev
            'ModName = Left(swModel.GetTitle, InStrRev(swModel.GetTitle, ".") - 1)
        End If

thanks a lot
