Minecraft Forums

I have an OLD minecraft save from a long time ago when i used to run a server. Me and some friends wanted to play on it again and check out this forgoten relic (last used 11/30/2010!) and were wondering if there is any way of converting it or something to make it playable. I put it into the .mc/saves folder but it doesnt show up on the in game world list.

any help is greatly appreciated! =D
