重命名文件以删除点后的文本

Question

我有这些文件：

JE.TR21201610011612514806.47250728
JE.TR21201610011613514807.91514463
JE.TR21201610011614514808.4107721050
JE.TR21201610011626514818.3578493139
JE.TR21201610011627514819.1032212591
JE.TR21201610011628514820.3663420052
JE.TR21201610011629514821.3388683091

我怎样才能将它们重命名为这个？

JE.TR21201610011612514806
JE.TR21201610011613514807
JE.TR21201610011614514808
JE.TR21201610011624514817
JE.TR21201610011626514818
JE.TR21201610011627514819
JE.TR21201610011628514820
JE.TR21201610011629514821
