Files within Multiple SubFolders and SubFolders Within It

Hey Guys,

I made a little research, and have found that the property actually belongs to BuiltinDocumentProperties of the workbook and can be made in use when file is open. Any ways to call use this property without opening the file..? Below code works and gets me the detail

Sub Test()
    MsgBox Workbooks.Open("<path>\Sample.xlsx").BuiltinDocumentProperties("Last Author")
End Sub
