I have a mod running on a server and i need to save some json files. For the save part i had no problem, but i noticed that these files are saved in the client folder instead that the server world folder. SO how can i point directly to the server folder and avoid these files being saved on the client? This is what i have right now

public static void saveFaction(Faction f) {
        JSONObject obj = new JSONObject();
        obj.put("Name", f.getName());
        obj.put("Owner", f.getOwner().toString());
        
        JSONArray members = new JSONArray();
        for(UUID u : f.getMembers()) {
            members.add(u.toString());
        }
        
        obj.put("Members", members);
        
        File dir = new File(DimensionManager.getCurrentSaveRootDirectory() + "/factions");
        if(!dir.exists())
            dir.mkdirs();
        
        try (FileWriter file = new FileWriter(dir + "/" + f.getName() + ".json")) {
            file.write(obj.toJSONString());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

I'm using JSON.Simple just to create correctly JSON files

Doesn't that save informations into a world data nbt file? Because if so is not what i'm looking for. Also i can't get it work, i've done this

	package com.cf.utils;
	import com.cf.CoreFaction;
	import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.world.World;
import net.minecraft.world.WorldSavedData;
import net.minecraft.world.storage.MapStorage;
	public class ExampleWorldSavedData extends WorldSavedData {
    private static final String DATA_NAME = CoreFaction.MODID + "_ExampleData";
	    public ExampleWorldSavedData() {
        super(DATA_NAME);
    }
	    public ExampleWorldSavedData(String s) {
        super(s);
    }
	    @Override
    public void readFromNBT(NBTTagCompound nbt) {
        System.out.println(nbt.getString("test"));
    }
	    @Override
    public NBTTagCompound writeToNBT(NBTTagCompound compound) {
        compound.setString("test", "prova");
        return compound;
    }
	    public static ExampleWorldSavedData get(World world) {
          MapStorage storage = world.getPerWorldStorage();
          ExampleWorldSavedData instance = (ExampleWorldSavedData) storage.getOrLoadData(ExampleWorldSavedData.class, DATA_NAME);
          if (instance == null) {
            instance = new ExampleWorldSavedData();
            storage.setData(DATA_NAME, instance);
          }
          return instance;
        }
}

But if i call the get method nothing happens and there is no new file in the world folder

Is not what i'm looking for just because i need something to be edited easy outside of the game (for example a server admin want to change the informations of one of these files but he wants to do it from the console, without logging into the game). That's why i need to save text files of some form, just to help the server managing

I forgot to mention that i store them in the world folder just to be more organized, but what if i want to save them generically in the server folder (like config files for example)? For instance, i want to create a subfolder into the server folder, but of course this has to be created only on the server, not on the client (in the .minecraft folder). How can i point directly to that? Is there a way to get the path to the server folder located on another pc?

I've done this

try {
            event.getSuggestedConfigurationFile().createNewFile();
        } catch (IOException e) {
            e.printStackTrace();
        }
 

But the config file has been created in the .minecraft folder and in the server config folder too.  How can i do so only in the server folder this file (or anything else) is created?

Yes, i want that file to exist on a dedicated server and using  FMLCommonHandler::getSide has solve the issue Thank you for your help
