How to close all the excel file open - excel

Question

I was running Marco to open all the .txt file in the list at ChDir.
And append data from the .txt to the Master file .xls.
But when run the script , the .txt file will be open with .xls in the PC .
If there are 5 .txt file , it will open 5 .xls file.
My question is how can i close all the 5 .xls file once script have append needed data into it?
I do not want to close it manually because the input file might be a lot in future. Thanks.

Answer 1

Try this:
For Each WkbkName In Application.Workbooks()
If WkbkName.Name <> ThisWorkbook.Name Then WkbkName.Close SaveChanges:=True
Next
(source)
EDIT: Since you're appending data to your 5 xls files, then I assume you need to save these workbooks before closing.

Answer 2

After opening the TXT file and copying the information to the Composite workbook, you should be able to close each one in sequence as you use it.
Sub Macro1()
Dim r As Long, c As Long, fp As String
fp = "C:\Users\csleow\Desktop\wafermap_stack" & Chr(92)
With Worksheets("file")
For r = 2 To 400
c = 1
If .Cells(r, c) = "" Then
r = 401
Else
With .Parent.OpenText(Filename:=fp & Cells(r, c), _
Origin:=437, StartRow:=1, DataType:=xlFixedWidth, _
FieldInfo:=Array(Array(0, 1), Array(5, 1), Array(10, 1), Array(15, 1), _
Array(20, 1), Array(25, 1), Array(30, 1), Array(35, 1), _
Array(40, 1), Array(45, 1), Array(50, 1), Array(55, 1), _
Array(60, 1), Array(65, 1), Array(70, 1), Array(75, 1), _
Array(80, 1), Array(85, 1), Array(90, 1), Array(94, 1), _
Array(99, 1), Array(104, 1), Array(109, 1), Array(114, 1), _
Array(119, 1), Array(124, 1), Array(129, 1), Array(134, 1), _

Array(159, 1), Array(164, 1), Array(169, 1), Array(174, 1), _
Array(179, 1), Array(184, 1), Array(189, 1), Array(194, 1), _
Array(199, 1), Array(204, 1), Array(209, 1), Array(214, 1), _
Array(219, 1), Array(224, 1), Array(229, 1), Array(234, 1), _
Array(239, 1), Array(244, 1), Array(249, 1), Array(254, 1), _
Array(259, 1), Array(264, 1), Array(269, 1), Array(274, 1), _
Array(279, 1), Array(284, 1), Array(289, 1), Array(294, 1), _
Array(299, 1), Array(304, 1), Array(309, 1), Array(315, 1), _

Array(360, 1)), _
TrailingMinusNumbers:=True)
.Worksheets(1).Cells(1, 1).CurrentRegion.Cells.Copy _
Destination:=Workbooks("Composite_9221.xlsm").Worksheets("Temp").Range("A1")
.Close savechanges:=False
End With
'done with the the TXT fle, close it
'I don't know what this does
Macro3
End If
Next r
End With
End Sub
I did not set up a full test environment to this but is cycled through the three TXT I created with limited fields.
