leftover chunks :/

In my plugin I have to delete terrain that has already been used by players(at the end of each match).
to do this i go through all the files in side the "getworld("arena").getFolder()" and delete them, and then i delete the world's whole folder. when i run the next game a new world is created, but all the chunks that were loaded in the previous world are still there. can someone explain to me how to get rid of previously loaded chunks and make sure the new world i create every time is in place of all chunks from te old one. thanks

 

Make sure that the whole world is unloaded before hand.

Code:

               
                /**for (Chunk c : Bukkit.getServer().getWorld("arena").getLoadedChunks()){
                    c.unload();
                }
                for (Chunk c : Bukkit.getServer().getWorld("arena_nether").getLoadedChunks()){
                    c.unload();
                }
                */
                Bukkit.getServer().unloadWorld("arena", false);
                Bukkit.getServer().unloadWorld("arena_nether", false);
                File f = (File) Bukkit.getWorld("arena").getWorldFolder();
                File fn = (File) Bukkit.getWorld("arena_nether").getWorldFolder();
                if (Bukkit.getWorld("arena").getWorldFolder().isDirectory()) {
                        for (File c : f.listFiles())
                          c.delete();
                        f.delete();
                }
                if (Bukkit.getWorld("arena_nether").getWorldFolder().isDirectory()) {
                    for (File c : fn.listFiles())
                      c.delete();
                    fn.delete();
              }

Did you check whether the folder is deleted with file manager?
