Iv'e downloaded a 3ds rom. Now, what i get are multiple rar files like .r00, .r01, and so on. When i try to open one it says: Cannot open. Then it says: Warning No archives found. Then it also says: Cannot open it because the file is being used by another process. I downloaded this using qBittorrent, so, i deleted qBittorrent. It didn't work. Could anyone tell me how to turn these rar files into only one rar file.
