I used the Update_All script by theypsilon in an attempt to get additional arcade cores and I also enabled the Arcade Organizer option. Now I found my arcade folder looks like this:
__Arcade
____Organized (folder)
____cores (folder)
____4D Warriors.mra
____lots of .mra files

At the beginning I assumed that perhaps the script only make soft-links of the .mra files and keep original files where they were, but I also went into the Organized folder and found a discrepancy between those mra in root Arcade folder and those in Organized folder (with some overlap).

So how should I make of the Aracade Organizer?

1. Am I safe to delete all those .mra files located at /Aracade root folder?
2. What should I do if I am to add new mra files, place them in the /Arcade folder and re-run the script?
3. are those files in /arcade the "whole library" of my mra files whereas those in Organized folder simply soft-links? If so, why certain mras are missing in the organized folder/root folder?

I tried looking through the github but found no explaination...

Thanks all in advance!
