You can use filecopy to copy the file to the archive directory.
eg.
FileCopy strOrigPath, strNewPath
The following will open an excel workbook clear the contents and save again.
Sub mClearExcelSheet()
Dim appExcel As New Excel.Application
Dim strPath As String
'Set file path
strPath = "C:\Test\Test.xls"
'Open excel
appExcel.Visible = True
'Open file
appExcel.Workbooks.Open strPath
'Select all cells
appExcel.Cells.Select
'Clear all cells
appExcel.Selection.ClearContents
'Set current selection to cell A1
appExcel.Range("A1"

.Select
'Save workbook
appExcel.ActiveWorkbook.Save
'Close workbook
appExcel.ActiveWorkbook.Close
'Quit excel
appExcel.Quit
'set variable to nothing
Set appExcel = Nothing
End Sub
There are two ways to write error-free programs; only the third one works.
