Need CODE help with function to List ALL folders AND all files

EDIT:Have now attempted to run the Tedinoz code found in forums here and am able to get filenames but only from two folders within the main folder... The two folders it's NOT reading, have several child folders. IS there a known limit to the number of child folders that can be acquired from Google App Script??

I have a script from @mesgarpour that I'm running on Google Drive to list out all assets therein. I have modified slightly to gain recursion down to the lowest file levels. But, while it runs, it is only listing the folders and subfolders AND NOT the files inside them. I am pasting the code below and would appreciate any help. AGAIN: I am looking for the script to list all files along with the other data that I'm getting.

Have attached image shows the style of folder names as well as the fact that only folders are being shown by the script.
