I had a Minecraft world on Minefold. I archived my Minecraft world just before Minefold closed about a year ago.
I'm trying now to open the world in my local Minecraft installation on OS X, but it doesn't show up in the worlds list.
To import it, I simply unzipped the archive from Minefold into my ~/Library/Application Support/minecraft/saves folder.
I'm running Minecraft 1.8, and I don't have any mods installed.
There's no error; the world just doesn't show up in my list of worlds after I click [Singleplayer] (or [Multiplayer]).
Now, the big clue is that the directory structures are different between my locally-created worlds and the world created on Minefold, but I can't figure out how to adapt the files to make them match:
This is a screenshot of my saves folder. I've circled in blue "local" and "minefold", which contain data files for the local and Minefold worlds, respectively.
I bracketed similar filenames in both worlds, but I'm flummoxed in that the Minefold version has three (3) sets of data files, whereas the local world has only one (1) set of files (even though I have visited Nether in the local world).
How do I load my old Minefold world locally?
