How To Open Files From Excel List Using VBA

I want to open files from an excel list.

Sub Openfile()
Dim wkbOne as Workbook
Set wkbOne = Application.Workbooks.Open(Filename:=Worksheets("Sheet1").Range("A1") & Worksheets("Sheet1").Range("B1")
'where "A1" is the path where the file located and "B1" is the file name.'
End Sub

When I run this it will work, but if I change to below it won't open all file in range, what's wrong with this?

Sub Openfile()
Dim wkbOne as Workbook
Set wkbOne = Application.Workbooks.Open(Filename:=Worksheets("Sheet1").Range("A1:A10") & Worksheets("Sheet1").Range("B1:B10")
End Sub
