how do game patches work?

Question

Let’s say a game file size is 500MB. If there is a 100MB patch, does the file size go to 600MB? Or does it patch what’s needs and deletes the old files?

Answer 1

it depends what that path does, it can add 100 MB of new content, or it can replace a 100 MB file to fix bugs or improve things, or anywhere in between, it could replace a 50 MB file and add 50 MB of new content
