Uninstall Issues, Storage Space Issues

So, i've had to uninstall a couple of times for various reasons. However, each time i've uninstalled, it doesn't remove the space it's been taking up somehow? For example i've had to free up more and more space each time i've reinstalled it for some reason? I can't find anywhere that can explain this to me or give me help. i have no more space on my computer and i have barely anything besides pso2 on it at this point.

When you uninstall, it creates a hidden back up folder that you need to manually delete. More details here: https://forum.pso2.com/topic/5634/my-ssd-is-shrinking-with-each-uninstall-and-reinstall-of-the-game
