Invisible files taking up space?

[epicninja]

I have a 128 gb ssd that i want to put a game on. However, i dont have enough space. Even with hidden files revealed, both operating system and and regular, if i selected all the files in my c drive, the computer puts them out a 48 gbs. However, based on that logic, i should have more than 50 gbs free, while i only have 27. What gives?

TLDR
There are invisible files taking up space, how do i see/get rid of them

It has windows and my program files on it, games are on my hdd. it is an ssd

I use a light and free program called TreeSize Free to see which files on my disk are taking up the most space. It allows you to sort them in descending order.

Also, disabling hibernation mode and reducing the size of your page file can free up a decent amount of space. Both are easy to do with plenty of instructions online.
