I want to reset my laptop to factory settings for a multitude of reasons. But it takes about 12-15 hours for me to download the entire game. I was wondering if it's possible to actually save the downloaded files somewhere (I have a big enough external) so that I can just copy them over after the wipe, and then install the game?

Haven't been able to find any info on this, but any help is appreciated!

(Also, side note, I don't want to install the game to an external drive, I want to put it back on my PC after the wipe, and am hoping to avoid the mega download times since I technically already have the game downloaded...)
