I'm trying to upload a world for me and my friends that we can play on. I have a zip file for the world and every time I upload it in the world tab, it doesn't appear in the file manager. When I upload it straight into the file manager, it's a ZIP file and I can't use the multiverse command on it. If I unzip the file, I don't know which specific file to upload into the file manager because it consists of lots of different folders. Help please?
