Fetch specific files from folder

I want fetch specific files (files name with timestamp ex test_3456_20240420_433636.xml) or current day’s files from folder (folder contains 10000 files) Kindly anyone help me on this scenario. 

Note:- 1. I don’t want to iterate loop 10000 times. (Reason - my bot will execute every 5 min so it will take more time for loop action only) 2. There is no option regex option in loop action with each file in folder.
