Macro That Automatica​lly Updates Data Itself In Excel

If you need to have a database that automatically updates itself. 
In fact, if you have a folder with different excel files, say folder Y (all the same form/template), and the first X cells of these files need to be extracted to another excel workbook (file Z). Every file represents 1 row in workbook  Z. But this should be done automatically.
So if I copy a new excel file in folder Y, the first X of this new excel file should automatically (can be with a ‘button demand’)  be copied into workbook Y.

 Option Explicit  
 Const cstFolder = "C:\Users\ATC0155\Documents\Toolbox\Excel\1208 20 selfupdate"  
 Const cstCols = 5  
 Sub DoUpdate()  
  Dim wks As Worksheet  
  Dim strFile As String  
  Dim appExcel As Excel.Application  
  Dim lngRow As Long  
  ' Prepare the sheet to receive the data  
  Set wks = Sheet1  
  ' Run through each file in the folder  
  strFile = Dir(cstFolder & "\*.xls*")  
  lngRow = 0  
  Do While strFile <> ""  
   If strFile <> ActiveWorkbook.Name Then  
    Set appExcel = CreateObject("Excel.Application")  
    appExcel.Workbooks.Open cstFolder & "\" & strFile  
    lngRow = lngRow + 1  
    appExcel.Sheets(1).Range(appExcel.Sheets(1).Cells( 1, 1), appExcel.Sheets(1).Cells(1, cstCols)).Copy  
    wks.Cells(lngRow, 1).PasteSpecial Paste:=xlPasteValues  
    wks.Cells(lngRow, cstCols + 1).Value = strFile  
    Set appExcel = Nothing  
   End If  
   strFile = Dir()  
  ' Tidy up  
  Set wks = Nothing
