Hi! I recently started a server to play with my cousin. I watched tutorials and followed the instructions to find my saves folder holding my worlds. But one of my worlds is not in the folder. Is it because it is an old version? If so how can I add it to my server? When I go into Minecraft and load it to the old version 1.6.4 forge I can access and play in my world but it still does not show up in the saves folder? Thanks for your time!
