Have VBA to set password to all xls files in one folder

[scorpio3st]

I need help with one macro:

Sub ProtectAll()
Dim xWorkBooks As Workbook
Dim xExitFile As String
Dim xPassWord As Variant
Dim xStrPath As String
Dim xFileDialog As FileDialog
Dim xFile As String
On Error Resume Next
Set xFileDialog = Application.FileDialog(msoFileDialogFolderPicker)
xFileDialog.AllowMultiSelect = False
xFileDialog.Title = "Select a folder [Kutools for Excel]"
If xFileDialog.Show = -1 Then
xStrPath = xFileDialog.SelectedItems(1)
End If
If xStrPath = "" Then
Exit Sub
Else
xStrPath = xStrPath + "\"
End If
xPassWord = Application.InputBox("Enter password", "Kutools for Excel", , , , , , 2)
If (xPassWord = False) Or (xPassWord = "") Then
MsgBox "Password cannot be blank!", vbInformation, "Kutools for Excel"
Exit Sub
End If

xExitFile = Dir(xStrPath & xFile)
On Error Resume Next
Application.ScreenUpdating = False
Do While xExitFile <> ""
Set xWorkBooks = Workbooks.Open(xStrPath & xExitFile)
Application.DisplayAlerts = False
xWorkBooks.SaveAs Filename:=xWorkBooks.FullName, Password:=xPassWord
Application.DisplayAlerts = True
Workbooks(xExitFile).Close False
Set xWorkBooks = Nothing
xExitFile = Dir
Loop
Application.ScreenUpdating = True
MsgBox "Successfully protect!", vbInformation, "Kutools for Excel"
End Sub

Now this Macro open every xls document and add password. Is it possible to add password without opening?
Thanks in advance.

That's not possible.
