Disable Message box during VBA Execution

Good day!

I searched from the net for the VBA that helps to copy data from a number of files (xls, xlsx, htm, txt, etc) saved in the same folder to another workbook and found the following one. It worked well except a message says "There is a large of amount of information on the Clipboard. Do you want to be able to paste this information into another program later?" kept popping up and I needed to click "Yes", "No" or "Cancel" multiple times so that the macro could go on. I found out from the net that the second codes below could serve that purpose. How does it fit in the first code code to turn off the pop-up message? If the second code is not applicable, how do I code to bypass the pop up?

Sub ProcessAllFiles()

    Dim sPath As String
    Dim Wb As Workbook
    Dim sFile As String
    

    
    sPath = "C:\Temp\"
     
    sFile = Dir(sPath & "*.xlsx")
    
    Application.ScreenUpdating = False
    
        Do While sFile <> ""
        

        Set Wb = Workbooks.Open(sPath & sFile)
        Sheets(1).Activate
        ActiveSheet.UsedRange.Copy
          
        Wb.Close SaveChanges:=False
        
        Range("A" & Rows.Count).End(xlUp).Offset(1, 0).PasteSpecial Paste:=xlPasteAll
        
      Application.CutCopyMode = False
      
        
    sFile = Dir
        
    Loop
    
   Rows("1:1").Delete Shift:=xlUp
   
   Application.ScreenUpdating = True
    
End Sub

application.displayalerts = false
ActiveWorkbook.Close savechanges:=false 'or true
application.displayalerts = true
