VBA Code To Run Macro In All Open Workbooks

I have a macro to get copy of sheet named "Doc Info" from workbook File 1 to active workbook.

I could do it for one file on any active workbook.

But what I would require is, upon executing this macro , i want this macro to get executed in all open workbooks( could be any numbers ).

I want to move copy of sheet from File 1 to all open workbooks ( which i am doing it manualy for every file )

All these open workbooks could be from any folder , wont be in same folder.

So logic is to execute my macro apply in all open workbooks in my computer.

Below is the code and i have attached file for test

HTML Code: 

Sub Copysheet()
Dim wSht As Worksheet
Dim wBk As Workbook
Dim wBk1 As Workbook

Set wBk = ActiveWorkbook 'Workbooks("File 2.xls")
Set wBk1 = Workbooks("File 1.xlsm")
Set wSht = wBk1.Sheets("Doc Info")

wSht.Copy before:=wBk.Sheets(1)

End Sub
