VBA中如何打开一个文件夹内的所有EXCEL文件?

'这段代码是读取一个文件夹下的所有文件,也可以根据扩展名筛选其它格式的.
'有了文件名,就是打开文件,获得每个文件的SHEET名字.然后写到你想要的地方

Sub Macro1()
Dim myDialog As FileDialog, oFile As Object, strName As String, n As Integer
Dim FSO As Object, myFolder As Object, myFiles As Object ,Dim fn$
Set myDialog = Application.FileDialog(msoFileDialogFolderPicker)
n = 1
With myDialog
If .Show <> -1 Then Exit Sub
Set FSO = CreateObject("Scripting.FileSystemObject") '这是文件夹选择,点选到你存放文件的那个
Set myFolder = FSO.GetFolder(.InitialFileName)
Set myFiles = myFolder.Files

For Each oFile In myFiles
strName = UCase(oFile.Name)
strName = VBA.Right(strName, 3)
If strName = "xls" Or strName = "XLS" Then '这是扩展名选择
'下面就可接着写打开文件读取数据再写入的语句了,如下:
fn = myFolder & "\" & oFile.Name
Workbooks.Open Filename:=fn
Worksheets(1).Select '假设你读取SHEET1的数据
RANGE_ = Range("A2:F50&qu
