Answer 1

It should look something like this:

Dim Filename As String
Dim lLastRow As Long
Dim wbDst As Workbook, wbSrce As Workbook
Dim wsDst As Worksheet

Set wsDst = ThisWorkbook.Worksheets("Sheet1")
Filename = Dir("C:\Users\You\Documents\Test\*.xlsx")
    
    Do While Filename <> ""
        Set wbSrce = Workbooks.Open(Filename)
        lLastRow = wsDst.UsedRange.Rows.Count + 1
            wbSrce.Sheets("B2B").UsedRange.Copy wsDst.Range("A" & lLastRow)
            wbSrce.Close savechanges:=False
        Filename = Dir
    Loop
