Just curious,how come you don't trust Winrar anymore? I've been using it for years and it's done nothing but help me download MMD models. Just curious to see since I know no one else who's had a problem with it.
Well, 7-zip is free, but a website is very convenient when you have zero memory left from downloading all those MMD models XD I just like 7-zip because you can extract as many as you want at the same time and can unzip rar files without having to convert them... Sorry if it sounds like I'm advertising XD
