How or what to compare files in Windows?

Question

Windows

Good day. I asked myself such a question. Let's say I have a game. Well, let it be Counter Strike. Let's say I play, play. And hop and the server on which I play has been updated. Accordingly, in order for me to play on it, I need to update the game. I restart steam, the game is updated everything is fine, I play. But is there any way to compare old and new files? Let's say I want to know which files have been updated, which files have been added, and everything related to the update. Is it possible with the help of any program to track, view and save only those files that have been updated?

You should always have a copy of the files
After updating, you make a copy again
Well, you compare the necessary copies with the last update
