You can do that with code like:
Code:
Sub Test()
' get the file's Creation date.
Dim FSO As Object
Dim oItem As Object
Dim StrFile As String
StrFile = ActiveWorkbook.FullName
If FSO Is Nothing Then Set FSO = CreateObject("Scripting.FileSystemObject")
Set oItem = FSO.GetFile(StrFile)
MsgBox "The date & time the file:" & vbCr & StrFile & vbCr & "was created is: " & oItem.DateCreated
End Sub
