Excel: Extract columns from one workbook to append to another workbook

I have a problem like this: I have multiple workbooks shared the same template with data: (let's say they're named "1.xlsx", "2.xlsx"...) A2: File# (eg: in ""1.xlsx" it's "File1") Field1 Field2 Field3 Field4 (the data stored in D3:G40)

And I have a fil开发者_运维知识库e name "Full.xlsx" File# Field1 Field2

Now I need to copy data D3:E40 from "1.xlsx", "2.xlsx"... to sheet1 of "Full.xlsx" (Field1, Field2), and their A2 goes to File#

For example, I have:

1.xlsx:
[A2] File1
[D2]Field1 [E2]Field2 [F2]Field3 [G2]Field4
[D3]aa [E3]bb [F3]cc [G3]dd
[D4]ee [E4]ff [F4]gg [G4]hh
...

2.xlsx:
[A2] File2
Field1 Field2 Field3 Field4
11 22 33 44
55 66 77 88
...

I need to have sheet1 in "Full.xlsx":

[A1]File# [B1]Filed1 [C1]Filed2
[A2]File1 [B2]aa [C2]bb
[A3]File1 [B3]ee [C3]ff
...
[A40]File2 [B40]11 [C40]22
[A41]File2 [B41]55 [C41]66
...

Can some one please tell me how to do this? (I'm using MS Excel 2010)

Update: I've finally written something that works (I'm new to VBA so it may be not the best solution)

Public Sub copyrows()
Dim FileNum As String
Dim LastRow As Long, i As Long, Counter As Integer
Dim Dest As Workbook
Set Dest = Workbooks("Full.xlsm")

FileNum = Cells(2, 1).Value

Dest.Activate

LastRow = Dest.Worksheets("Sheet1").Range("C65536").End(xlUp).Row + 1
i = LastRow

For Counter = 3 To 40
    Dest.Worksheets("Sheet1").Cells(i, 1).Value = FileNum
    i = i + 1
Next

ThisWorkbook.Activate
ThisWorkbook.Worksheets("Sheet1").Range("D3", "E40").Copy
Dest.Activate
Dest.Worksheets("Sheet1").Range("B" & LastRow, "C" & i).Select
Selection.PasteSpecial Paste:=xlPasteAll, Operation:=xlNone, SkipBlanks:= _
        False, Transpose:=False
End Sub

Thank everyone for your concern!
