Dynamically catching new file creations

Dynamically catching new file creations

I have a team folder with many subfolders, and in those folders we add new documents all the time. I'd like to have a workflow or script to notify me (and then take other actions) when a file is added anywhere in that structure that ends in "summary.txt".

What would be the best approach for this? Zoho Flow doesn't seem to monitor sub folders for changes, for example as best I can tell, but that would have been a great answer.

Thoughts?
