   Master.Columns.Delete
   'MsgBox "Point to the folder containing all the files in the next dialog - then click Cancel"
   'Application.GetOpenFilename
   On Error Resume Next
   With Application.FileSearch
       .NewSearch
       .LookIn = "C:\Excel Sheets"
       .FileType = msoFileTypeExcelWorkbooks
       .Execute
       'For i = 1 To .FoundFiles.Count
       For i = 1 To 19
           Workbooks.Open .FoundFiles(i), False, True
           Err.Clear
           Sheets("Sheet1").Activate
           If Err.Number <> 0 Then
               ActiveWorkbook.Close False
               GoTo NextWB
           End If
           l = Master.UsedRange.Rows.Count
           ActiveSheet.UsedRange.Copy
           Master.Cells(l + 1, 1).PasteSpecial
           Application.CutCopyMode = False
           'ActiveWorkbook.Close False
NextWB:
