I have a macro I built to pull data from two different work books. The issue is they are the same name almost.

One is:
"One_Way_Flow.xlsm"

and the other is

"One_Way_Flow.xls"

I am trying to find a workaround because they thy are two large to save and rename first. Is there a way to make it I put

Windows("One_Way_Flow.xls").Activate

It will not pull the one with the s on the end?
