… Say I need to download an update file to use CoD. It will spend some time downloading the file, then it spends even longer “copying” the file. I don’t get it… I already have the file. How in the fuck could copying the file get me something that I don’t already have? Why can’t I just use the file I have already, that I just got??? Why can’t it just use the downloaded file to update?!?! I can’t wrap my head around it. Some software engineer out there… please make me understand how this could possibly make sense!

It is rather simple, you need to make a copy/uncompress the files you want to update, so you in the event of some error, power outage, corrupted download, the original files stay intact and you can roll-back everything. When complete they can check if the files are updated correctly
If you update the game files directly, you run the chance that your game files going to get corrupted and you need to delete the game and redownload it and if you are unlucky update again.
So you I ask you, you want to do the update fast or you want to do it right?
