如何使用不同的密码保护同一文件夹中的excel工作簿

如何解决如何使用不同的密码保护同一文件夹中的excel工作簿

我想用不同的密码保护同一文件夹中的 Excel 工作簿。我有以下代码，但只有在工作簿受相同密码保护的情况下才能使用它。怎么改？

Public Sub addPassword()
    Dim FSO As Object
    Dim folder As Object,subfolder As Object
    Dim wb As Object
    
    Set FSO = CreateObject("Scripting.FileSystemObject")
    folderPath = "C:\Users\User\Desktop\Test"
    Set folder = FSO.GetFolder(folderPath)
    
    With Application
        .displayAlerts = False
        .ScreenUpdating = False
        .EnableEvents = False
        .AskToUpdateLinks = False
    End With
        
    For Each wb In folder.Files
        If Right(wb.Name,3) = "xls" Or Right(wb.Name,4) = "xlsx" Or Right(wb.Name,4) = "xlsm" Then
            Set masterWB = Workbooks.Open(wb)
            ActiveWorkbook.SaveAs Filename:=Application.ActiveWorkbook.FullName,Password:="123"
            ActiveWorkbook.Close True
        End If
    Next
    For Each subfolder In folder.SubFolders
        For Each wb In subfolder.Files
            If Right(wb.Name,4) = "xlsm" Then
                Set masterWB = Workbooks.Open(wb)
                ActiveWorkbook.SaveAs Filename:=Application.ActiveWorkbook.FullName,Password:="123"
                ActiveWorkbook.Close True
            End If
        Next
    Next
    With Application
        .displayAlerts = True
        .ScreenUpdating = True
        .EnableEvents = True
        .AskToUpdateLinks = True
    End With
End Sub
