The data folder isn't renamed because I don't know of anyone who's ever modified it, and the properties folder shouldn't be an issue because it renames both main.pak AND the folders if it can find them. My main.pak format mods are okay because I actually compiled those necessary files INTO main.pak so they don't even need to be there.
