What can I delete?

This isn't exactly a problem, but the thing is that I'm trying to clean out unwanted files and folders just to make for more room on my computer and what-not, and I came upon the folder I had especially created for the files that come when you extract the .zip. I have all the expansions that have been released, and all of these folders together are a total of 123 gb. I'm aware that deleting this these files will (most likely) not effect my game at all, but I want to keep them in case I ever have to uninstall anything for glitch purposes, and to have them there instead of having to re-download them from the website which can take hours. I've tried simply keeping the Installer file but when I do that it gives me an error and says that it's missing some other files.

Any information on this would be helpful.

Personally, I'd recommend getting rid of the separate files, and keeping a copy of all of the zip files instead, as those are compressed. You could even get a 16GB flash drive and fit most of the .zip files on there, so it's taking up even less space on your computer (after you seed for a while, of course)

Sorry for the late reply, but I've got to say that that is really smart. I'm glad I kept all of the .zip files. Thank you! And haha yes of course.

Well actually it'd only cut the size in half, but 60-something gigs is still a big difference from 123.
