I'm talking about a PC refresh (not factory reset), so it says it will keep files and stuff. So is Minecraft treated as a file or app? What about the saved worlds in Minecraft, are those files or part of the app? I guess I don't care if it deletes Minecraft, if I can still download it again and keep my the old worlds. BUt I do care if it deletes Minecraft along with the worlds.
P.S. I don't play or care that much for Minecraft. My brother doesn't want me to refresh the PC because he is afraid it will delete Minecraft and/or the worlds.
