How to execute macro of other workbook in the present workbook, during automation


I want to execute macro which is other workbook(excel), In the current workbook. I wrote a macro for deleting rows from 1 to 11. Here is the code

Sub Macro1()
End Sub
This code is in my Add.xlsm file.

I need to execute this code for each and every excel file that I download during automation. I tried executing macro but it is not working fine. Can any one provide any better solution.
Thanks and Regrds,

Your question is answered here. You can call macro from any workbook.
