Note* Once Compact GUI is done with the game you pick, go to the folder in Windows where the game is at, highlight the very same folder of the game you use in Compact GUI, then hold shift while pressing right mouse a menu going to show open Powershell. Once Powershell is open enter compact /c /s & wait until it's done. after you compress it, it marks the folder so that any changes get compressed as well. *This step is for games that update a lot & does not break the compressed folder each time there a update. If you want to know if compressed work in Powershell, you going to see two little blue arrows in the folder. now when the game update it's going to compress the file in realtime so there no need to rerun Compact GUI.
