We can take that main macro and turn it into a subroutine that is called by another macro. We feed in the folders to the macro and work our way deeper and deeper until all folders are processed.
Then we create a main macro to set things in motion... create a blank workbook and feed in the main folder name. That is fed to a "loop" macro that first processes that main folder, then starts detecting folders and restarting the "loop" again in each folder, deeper and deeper until all are processed.
