how to combine code

Hello. This first code opens all files in a folder and renames the first tab in each open file. The second adds the content from each tab into one tab. Is there a way that I can combine the two codes into one? So taht I don't have to run two macros?

Oh cool, but is my code inefficient? That is, would it be better to include the second piece of code as part of the first?
