Below is code that I found on a site by Ron De Bruin. It seems to work well for what I am asking it to, but I am curious if there is a way to speed it up. The folder that it is pulling information from has several hundred files and it takes a great deal of time. I'm not sure if perhaps I do not have the right code for this type of process or if there is anything I can do other than sit and wait for it to update. Also I was wondering if there is a way to modify it to only update new files.... Help is appreciated. Thanks!

Sub Example1()
Dim basebook As Workbook
Dim mybook As Workbook
Dim rnum As Long
Dim FNames As String
Dim MyPath As String
Dim SaveDriveDir As String
Dim Cnum As Integer
Dim cell As Range


SaveDriveDir = CurDir
MyPath = "C:\Documents and Settings...."
ChDrive MyPath
ChDir MyPath

FNames = Dir("*.xls")
If Len(FNames) = 0 Then
MsgBox "No files in the Directory"
ChDrive SaveDriveDir
ChDir SaveDriveDir
Exit Sub
End If

Application.ScreenUpdating = False
Set basebook = ThisWorkbook
'clear all cells on the first sheet
'basebook.Worksheets(1).Cells.Clear

rnum = 2

Do While FNames <> ""
Set mybook = Workbooks.Open(FNames)

Cnum = 1
For Each cell In mybook.Worksheets(1).Range("D4,I4,C6,D6")
basebook.Worksheets(1).Cells(rnum, Cnum).Value = cell.Value
Cnum = Cnum + 1
Next cell

mybook.Close False
rnum = rnum + 1
FNames = Dir()
Loop

ChDrive SaveDriveDir
ChDir SaveDriveDir
Application.ScreenUpdating = False
End Sub
