Searching for a file in multiple directories

I am an ALteryx beginner. Here is my problem:

I am looking for a specific XML file, for the sake of this example lets call it sample.xml. I know I can use the Directory tool and use the column FileName from the output in the Filter tool and put a condition for FileName = sample.xml and find the file in 1 folder. But my problem is I have a bunch of folder and in some cases folders within folders and I want to search for this file in all those folders. Basically my question boils down to how do you traverse through multiple directories in Alteryx to perform operations? 

Thank you.
