If this is a question I shouldn't be asking feel free to notify me and delete. I've watched several videos and read a few posts on the various files that come in an extracted ISO (like the one required for GX2). The thing I get confused about is that some videos and guides don't use all of the files in the ISO. I've seen some only use content and code, or put both of those into a folder called data. And then I've seen some people say some games only come out a certain size, say 2.5GB, and yet whenever I download an ISO for the same game, it far exceeds the size, say 8GB. Why is this? Is there some folders or files that are unneeded that I can delete to trim down the size?
