Duplicate a world

Hi, So I was wondering if there is any way to "duplicate" a world. Basically, I'm going to have a defalt world, and it is going to be duplicated, the duped version will be edited and such, then i want to get rid of the duped version, but still keep the original... any way to do this?

 

Does java have a copy folder function? ill check...

i found a snippet that might be helpfull to you

Code:

package com.mkyong.file;
 
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
 
public class CopyDirectoryExample
{
    public static void main(String[] args)
    {	
    	File srcFolder = new File("c:\\mkyong");
    	File destFolder = new File("c:\\mkyong-new");
 
    	//make sure source exists
    	if(!srcFolder.exists()){
 
           System.out.println("Directory does not exist.");
           //just exit
           System.exit(0);
 
        }else{
 
           try{
        	copyFolder(srcFolder,destFolder);
           }catch(IOException e){
        	e.printStackTrace();
        	//error, just exit
                System.exit(0);
           }
        }
 
    	System.out.println("Done");
    }
 
    public static void copyFolder(File src, File dest)
    	throws IOException{
 
    	if(src.isDirectory()){
 
    		//if directory not exists, create it
    		if(!dest.exists()){
    		   dest.mkdir();
    		   System.out.println("Directory copied from " 
                              + src + "  to " + dest);
    		}
 
    		//list all the directory contents
    		String files[] = src.list();
 
    		for (String file : files) {
    		   //construct the src and dest file structure
    		   File srcFile = new File(src, file);
    		   File destFile = new File(dest, file);
    		   //recursive copy
    		   copyFolder(srcFile,destFile);
    		}
 
    	}else{
    		//if file, then copy it
    		//Use bytes stream to support all file types
    		InputStream in = new FileInputStream(src);
    	        OutputStream out = new FileOutputStream(dest); 
 
    	        byte[] buffer = new byte[1024];
 
    	        int length;
    	        //copy the file content in bytes 
    	        while ((length = in.read(buffer)) > 0){
    	    	   out.write(buffer, 0, length);
    	        }
 
    	        in.close();
    	        out.close();
    	        System.out.println("File copied from " + src + " to " + dest);
    	}
    }
}

Hmm, let me do a little modding and see if I can get this to work... will post sometime tomorrow

BTW I'm just throwing this out there, java should implement this in the java.io , seems like something basic that is really useful .

 

all right i hope it helps you

 

wont work 100% you also copiing the uuid.dat, 2 world cannot have the same uuid

 

The problem is that the UIDs are duplicate.

Is there a way to fix this?
EDIT:
nvm, found a way to fix it.
The trick is to delete the world's uid.dat after you created the new world folder, so bukkit will make a new UUID when you load the world.
