I still don't get Apples bizarre new snapshot system.

What i know is that a few years ago and back i would never have this problem, but now i'm often having gigantic snapshot files taking up extreme amounts of space like 100 gigabytes on my 500gb Macbook. Probably because i work with large files. And this is not explained to anyone unless they research why the hell deleting files does not give more space in some apple support forum.

OSX is stil my go to OS but these unexplained magic elements with no explanation are getting completely out of hand now.
