Pak File Loader Plugin

This looks amazing! Is there an early version of this for 4.18?
OR is it possible an 4.18 baked (but not encrypted) pak might be accessible using this in 4.22?

Does this actually allow you to load your old objects back in engine or does it just pass them through to the new bake? (I made my first game in 4.18, have non e of my old files but can access the pak with Gildors tools etc.)

Can this load Blueprints? Maps/Levels audio or? Into the Editor? meaning: Could one take their first game made in 4.18, (for which they long ago lost all the Editor Assets) and load everything into 4.22 (or 4.24…) then rebake the game with new music better lighting and a VR Pawn (for instance?)

THANK YOU!
